Abstract (sommario):

Background Several series of experiments from our research group have shown ultraviolet (UV) light transmission of homeopathic preparations to slightly but significantly differ from controls. We now investigated whether visible and near infrared spectroscopy were also useful for exploring properties of homeopathic preparations. Materials and methods Homeopathic preparations of copper sulfate (CuSO4), hypericum and sulfur (S8) were produced in 30 sequential steps of 1:100 dilutions (c-preparations). As controls, succussed potentization medium was used. Transmission of the samples from 190-1100nm was measured 4 times on 5 days with a double beam Shimadzu UV PC 1601 spectrophotometer. To correct for the daily variations of the spectrophotometer, transmission of the samples at each nm was divided by the average transmission of the controls. Median transmissions of the samples were calculated for the ranges of 190-340nm (near and middle UV), 340-640nm (visible light without red), and 640-1100nm (red and near infrared). Differences in the median transmission between potency levels from 6c to 30c were determined using Kruskal-Wallis and Jonckheere-Terpstra tests. Results Differences in transmissions of the various potency levels were more pronounced in the UV range than in the visible or red/near infrared range. The Kruskal-Wallis test revealed significant differences for homeopathic preparations of CuSO4, hypericum and S8 in the UV range (p=0.032, 0.008, 0.009, respectively) and of S8 in the visible range (p=0.026). Jonckheere's test showed a tendency towards ascending medians with ascending potency levels for CuSO4 in the UV range (p=0.080). Significant trends were revealed for hypericum in the visible range (p=0.042, descending medians) and S8 in the UV range (p=0.015, ascending medians). Conclusion UV spectroscopy seemed to be more suitable for investigating homeopathic preparations than visible or near infrared spectroscopy, since differences in transmission were more pronounced in the UV range.

Abstract (sommario):

A number of commercially available art protection products have been compared and assessed for their suitability as UV blocking filters in the application of “visible light” photocatalytic research. Many groups claiming visible light photocatalytic success employ filters to block out stray UV radiation in order to justify that their photocatalysts are indeed visible light photocatalysts and not UV light photocatalysts. These filters come in varying degrees of ability and price and many authors fail to correctly characterise their filters in individual papers. The use of effective filters to prevent both false positive and false negative results is important to maintain scientific rigor and create accurate understanding of the subject. The optimum UV filter would have the highest UV blocking properties (<390 nm) and simultaneously the highest visible light transmission (390–750 nm). Single and double layers of each of the glass products were assessed as well as laminate products. The conclusions show an inexpensive and highly effective setup for the conduction of visible light photochemistry that should be incorporated as a standard part in any researcher’s work where the claim of visible light activity is made.

Abstract (sommario):

ABSTRACT Photoreactivation was observed in airborne Mycobacterium parafortuitum exposed concurrently to UV radiation (254 nm) and visible light. Photoreactivation rates of airborne cells increased with increasing relative humidity (RH) and decreased with increasing UV dose. Under a constant UV dose with visible light absent, the UV inactivation rate of airborne M. parafortuitum cells decreased by a factor of 4 as RH increased from 40 to 95%; however, under identical conditions with visible light present, the UV inactivation rate of airborne cells decreased only by a factor of 2. When irradiated in the absence of visible light, cellular cyclobutane thymine dimer content of UV-irradiated airborne M. parafortuitum and Serratia marcescens increased in response to RH increases. Results suggest that, unlike in waterborne bacteria, cyclobutane thymine dimers are not the most significant form of UV-induced DNA damage incurred by airborne bacteria and that the distribution of DNA photoproducts incorporated into UV-irradiated airborne cells is a function of RH.

Abstract (sommario):

The construction of heterostructured photocatalyst with an appropriate energy band structure will help realize highly efficient photo-excited charge separation. In this study, ternary CuO/CeO2/ZnO nano-particle (NP) composites were synthesized by a facile two-step sol-gel method, which exhibit significantly enhanced photocatalytic degradation performance for various organic pollutants under UV and visible light excitation. The photo-responses to both UV and visible light, as well as the visible light absorption and utilization rates of ZnO are found to be synergistically intensified by CeO2 and CuO co-coupling. The first-order kinetic constants (K) of 3%CuO/CeO2/ZnO for methylene blue (MB) degradation are ~3.9, ~4.1 and ~4.8 times higher than ZnO under UV light, visible light and simulated sunlight illumination, respectively. The roles of CuO and CeO2 in optical properties and photo-degradation under UV and visible light were explored. Besides, the photogenic holes (h+) of ZnO, CeO2, and the produced hydroxyl radicals (·OH) are proved to be the main active species under UV light. Dissimilarly, under visible light, the superoxide radicals (·O2−) formed by the reactions between oxygen molecules and the photo-generated electrons (e−) of CuO moving towards the catalysts surface are also found to be important for promoting dye decomposition. The improved photo-responses, the well-matched band structure that facilitates charge transfer processes, and the highly efficient utilization of the photo-excited carriers of the ternary nano-heterostructure are suggested to be the key factors for the remarkable enhancement of photocatalytic performance of ZnO nano-photocatalyst. This work offers a low-cost strategy to acquire highly active UV and visible light-driven photocatalyst.

Abstract (sommario):

This paper presents a silicon ultraviolet radiation sensor with over 90% UV internal quantum efficiency (QE) and high selectivity to the UV waveband without using optical filters. The sensor was developed for applications that require UV measurement under strong background visible and near-infrared (NIR) lights, such as solar UV measurement, UV-C monitoring in greenhouses or automated factories, and so on. The developed sensor is composed of monolithically formed silicon photodiodes with different spectral sensitivities: a highly UV responsive photodiode with internal quantum efficiency (QE) of nearly 100% for UV light, and a lowly UV responsive photodiode with UV internal QE lower than 10%. The photodiodes were optimized to match their visible and NIR light responsivity, and the UV signal is extracted from the background radiation by using the differential spectral response method. With this approach, an internal QE of over 90% for UV light was obtained, with a residual internal QE to non-UV light lower than 20% for 400 nm, 5% for 500 nm, 2% for 600 nm and 0.6% to NIR light. The developed sensor showed no responsivity degradation after exposure towards strong UV light. It was confirmed by the simulation results that the residual responsivity is further suppressed by employing an on-chip band-rejection optical layer consisting of several layers of silicon oxide and silicon nitride films.

Abstract (sommario):

Phenol (C6H5OH) is a common contaminant in wastewater. In certain concentrations, phenol can inhibit the activity of microorganisms and give adverse effects tohumanhealth, such as liver and kidney damage, perfect heart rate, and lower blood pressure. In this study, phenol was degraded with andwithoutN-doped TiO2under photolysis UV-light (10 Watts, λ = 365 nm) and visible-light (13 watt Philips, lux= 1400, λ = 465-640 nm)irradiation. The reductionof phenol concentrationwas measured by a UV-Vis spectrophotometer at a wavelength 200-400 nm. Some parameters such as catalyst dose, irradiation timesand type of light sources were studied. The XRD and DRS UV-Vis characterization confirmthat the nitrogen modified of titania catalyst potentially actives in visible-light. The N-doped TiO2is able to catalyze and improve the efficiency of phenol degradation in photocatalysissystem. Phenol with initialconcentration 8 mg/L was degraded by 33.89% and 30.51% without catalyst and increased to be 90.8% and 67.80%by additionof 15 mg N-doped TiO2catalyst under UV-light and visible-lightfor 210 minutes photolysis, respectively. From the results,irradiation using UV-light achieveshigherefficiency than visible-lightonphenol degradation.

Abstract (sommario):

The diffuse galactic light, resulting from the coherent scattering of galactic starlight by dust grains contained in the general interstellar medium, has been the subject of active investigation for nearly 60 years. The separation of the diffuse galactic light from the other sources contributing to the light from the night sky has proven difficult, and different attempts at measuring the intensity and galactic distribution of the diffuse galactic light, both in the visible and the UV, are reviewed here. The interpretation of such measurements in terms of average scattering properties of interstellar grains is subject to additional uncertainties, stemming from the high degree of idealization imposed on the galaxy models used to study the radiative transfer problem. In the visible, the observations are more nearly definitive and the model problems less severe; reasonably consistent scattering properties have therefore been derived for this spectral region. In the UV, the situation is considerably less satisfactory, mainly due to a lack of sufficiently extensive, reliable measurements of the diffuse galactic light intensity at λ < 200 nm. A dedicated space mission may be the required solution. The radiative transfer in the UV presents serious difficulties due to the increasing opacity of the interstellar medium with shorter wavelengths and the resulting growing importance of the local galactic structure.

Abstract (sommario):

To simultaneously achieve the high visible transparency and enhance the ultraviolet (UV)-blocking performance of displays, inorganic–organic hybrid nanoparticles, comprising TiO2 as a core and poly(methyl methacrylate) (PMMA) as a shell, were uniformly incorporated into the optically clear adhesive (OCA) used in the front of a display device. The highly refractive TiO2 nanocore could selectively scatter UV rays, which degrade the display performance, owing to the differences in the refractive indices between the inorganic particles and PMMA matrix, thereby offering an improved UV protection property to the adhesive film. Moreover, the organic PMMA nanoshell maintained the high visible light transmittance of the pristine OCA film via the prevention of particle agglomeration. To examine the effect of the PMMA nanoshell and nanoparticle size on the optical properties of the adhesive films, the OCA films embedded with only TiO2 nanoparticles or hybrid nanoparticles with different particle sizes were prepared using a roll-to-roll process, and characterized in the range of UV and visible lights using UV-visible spectroscopy. It is experimentally revealed that the adhesive film including small TiO2/PMMA hybrid nanoparticles at an extremely low content exhibited enhanced UV-blocking properties and increased visible light transmittance compared to that with only TiO2 nanoparticles.

Abstract (sommario):

The development of visible light-sensitive photocatalytic materials is being investigated. In this study, the anatase and rutile-C60composites were prepared by solution process. The characterization of the samples was conducted by using XRD, UV-vis, FT-IR, Raman, and TEM. The photocatalytic activity of the samples was evaluated by the decolorization of the methylene blue. From the results of the Raman, FT-IR, and XRD, the existence of the C60was confirmed in the samples. The C60was modified on the anatase or rutile particle as a cluster. The C60didn't have the photocatalytic activity under UV and visible light. The anatase and rutile-C60composites exhibited lower photocatalytic activity than the anatase and rutile under UV light. The anatase-C60exhibited also lower activity than the anatase under visible light. On the other hand, the rutile-C60exhibited higher activity than the rutile under visible light. It is considered that the photogenerated electrons can transfer from the C60to the rutile under visible light irradiation.

Abstract (sommario):

Perovskite-type nitrogen-doped SrTiO3nanoparticles of 50–80 nm in diameter were successfully synthesized by the solvothermal of Ti(OC3H7)4, SrCl2⋅6H2O, and hexamethylenetetramine in KOH aqueous solution. Nitrogen-doped SrTiO3showed excellent photocatalytic activity under both UV and visible light irradiation, that is, the photocatalytic activity of N-doped SrTiO3for DeNOxreaction was greater than that of SrTiO3and commercial TiO2(Degussa P25) in both visible light region (>510 nm) and UV light region (>290 nm). The excellent visible light photocatalytic activity of this substance was caused by generating a new band gap that absorbs visible light.

Abstract (sommario):

Spin coated films of a chiral comb-like liquid crystalline copolymer containing azobenzene chromophores in its side chains are optically isotropic in their twisted smectic-like glassy state. In contact with a nematic liquid crystal (5CB, E7, MBBA) they provide a degenerate planar orientation. When irradiated by unpolarized UV light, they orient the same nematics homeotropically. Treated with linearly polarized UV light they orient nematics homogeneously with the director along the electric vector of the exciting light. After a combined irradiation first with unpolarized UV light and then with linearly polarized visible light, the films again provide a homogeneous liquid crystal orientation, this time with the director perpendicular to the visible light electric vector. The phenomena observed are related to the light induced optical anisotropy. Two main processes are responsible for the anisotropy (1) a UV light depletion of trans-isomers of the azobenzene chromophores from the chosen direction and (2) a reorientation of the chromophores by polarized visible light.

A new type of hybrid TiO₂–Ag nanocluster (NC) photoelectrode exhibits wavelength-switchable photocurrent by tuning the light wavelength from ultraviolet (UV) to visible light. The combination of UV-active TiO₂ and visible-light-active Ag NCs with photoelectrochemical behaviour leads to the unique switchable photocurrent in the system.

Abstract (sommario):

This paper presents a complementary metal-oxide-semiconductor (CMOS) image sensor (CIS) capable of capturing UV-selective and visible light images simultaneously by a single exposure and without employing optical filters, suitable for applications that require simultaneous UV and visible light imaging, or UV imaging in variable light environment. The developed CIS is composed by high and low UV sensitivity pixel types, arranged alternately in a checker pattern. Both pixel types were designed to have matching sensitivities for non-UV light. The UV-selective image is captured by extracting the differential spectral response between adjacent pixels, while the visible light image is captured simultaneously by the low UV sensitivity pixels. Also, to achieve high conversion gain and wide dynamic range simultaneously, the lateral overflow integration capacitor (LOFIC) technology was introduced in both pixel types. The developed CIS has a pixel pitch of 5.6 µm and exhibits 172 µV/e− conversion gain, 131 ke− full well capacity (FWC), and 92.3 dB dynamic range. The spectral sensitivity ranges of the high and low UV sensitivity pixels are of 200–750 nm and 390–750 nm, respectively. The resulting sensitivity range after the differential spectral response extraction is of 200–480 nm. This paper presents details regarding the CIS pixels structures, doping profiles, device simulations, and the measurement results for photoelectric response and spectral sensitivity for both pixel types. Also, sample images of UV-selective and visible spectral imaging using the developed CIS are presented.

Abstract β-Bi2O3semiconductor nanoparticles synthesized by solution combustion method. The as-synthesized sample was systematically characterized by several techniques, including PXRD, DLS, Raman spectrometry, SEM, and DRS-UV-vis spectroscopy. PXRD and Raman analyses confirmed high crystallinity and phase purity of the prepared β-Bi2O3. SEM and DLS showed the morphology and the agglomeration of β-Bi2O3nanoparticles.DRS-UV-Vis showed the enhanced visible light absorption toward the visible light range with bandgap 2.43 eV. Significantly, β-Bi2O3 nanoparticles demonstrated outstanding visible-light photocatalytic properties, revealed enhanced methylene blue (MB) dye degradation. 91% of the dye content was degraded by 30 minutes under 50W visible LED light irradiation, which could be attributed to enhanced visible light absorption and the smaller size of the synthesized nanoparticles.

Abstract (sommario):

Synthesis of magnetic photocatalyst, Fe3O4/TiO2-Ag, with characterization and photoactivity examination have been investigated. The synthesis was initiated by preparation of Fe3O4 particles using coprecipitation method. The Fe3O4 particles were then coated with TiO2-Ag, weight ratios of concentrations Silver dopant were varied from 1 to 3, 5 and 7 wt%. The Fe3O4/TiO2-Ag was characterized by FTIR, XRD, TEM, SEM-EDX, DR UV-visible and VSM methods. The degradation of metanil yellow solution was performed under exposure to UV, visible light and dark condition at optimum condition. The Fe3O4 and anatase diffraction peaks were presence on the X-ray diffractogram. The Fe3O4/TiO2-Ag was responsive to visible light, according to DR UV-Vis spectra. The Fe3O4/TiO2-Ag band gap energy was 2.49, 2.30, 2.00, and 2.46 eV, respectively, with dopant concentrations of 1; 3; 5; and 7%. Metanil yellow solution can be photodegraded for 180 minutes at a pH of 2.3. The Fe3O4/TiO2-Ag has the highest ability to metanil yellow photodegradation with dopant concentration of 5% gave degradation yield of 82.18% and 72.53% under UV and visible irradiation, respectively. With K values of 0.52 g mg-1 min-1 under visible light and 0.5255 g mg-1 min-1 under UV light, the degradation kinetics of methanyl yellow dye followed Ho and McKay's kinetic model. The Fe3O4/TiO2-Ag material exhibited magnetic characteristics that could be applied under visible light and reused.

Abstract (sommario):

The solar light consists of ultraviolet, visible and infrared ray. The ultraviolet and infrared rays, unlike visible ray, are not benefit to photosynthesis. Inorganic ultraviolet absorbing materials are mostly in crystallised phase such as TiO2, ZnO and CeO2 which caused lower transmittion in visible range. As known that, the commercial organic UV absorbers can absorb only the appointed UV wavelength. TiO2 emulsion for ultraviolet blocking was synthesized in this project in order to overcome such poor transmittion behavior. The preparative TiO2 emulsion can absorb UV completely without interfering the visible light transmittance. This is because the synthesized TiO2 via emulsion method was mainly an amorphous phase. The obtained composite film containing amorphous phase of TiO2 shows 80-90% transmittance of the visible light, 20-70% absorbance of ultraviolet A and 70-95 % absorbance of ultraviolet B.

In this study, reduced graphene oxide and Titanium dioxide (RGO/TiO2) photocatalysts were synthesized by ultrasonic mixing. The prepared RGO/TiO2 photocatalysts were characterized by scanning electron microscopy, X-ray diffraction spectroscopy and UV-visible spectrophotometry. The performance of the RGO/TiO2 photocatalysts was studied under UV and visible light evaluated by the degradation of the methylene blue (MB). In the photocatalytic process, all the RGO/TiO2 photocatalysts showed better photocatalytic activity than commercial TiO2 nanopowder (P25) under visible light, which showed that RGO could reduce electron-hole recombination on the TiO2, led to the improvement of the photocatalytic performance under visible light

Abstract (sommario):

Most of reported polymeric light-responsive nanocarriers make use of UV light to trigger morphological changes and the subsequent release of encapsulated cargoes. Moving from UV- to visible-responsive units is interesting for the potential biomedical applications of these materials. Herein we report the synthesis by ring opening polymerization (ROP) of a series of amphiphilic diblock copolymers, into which either UV or visible responsive azobenzenes have been introduced via copper(I) catalyzed azide-alkyne cycloaddition (CuAAC). These copolymers are able to self-assemble into spherical micelles or vesicles when dispersed in water. The study of the response of the self-assemblies upon UV (365 nm) or visible (530 or 625 nm) light irradiation has been studied by Transmission Electron Microscopy (TEM), Cryogenic Transmission Electron Microscopy (Cryo-TEM), and Dynamic Light Scattering (DLS) studies. Encapsulation of Nile Red, in micelles and vesicles, and Rhodamine B, in vesicles, and its light-stimulated release has been studied by fluorescence spectroscopy and confocal microscopy. Appreciable morphological changes have been induced with green light, and the subsequent release of encapsulated cargoes upon green light irradiation has been confirmed.

Abstract (sommario):

Different tri-doped TiO2 photocatalysts (Fe-N-P/TiO2, Fe-N-S/TiO2, Fe-Pr-N/TiO2, Pr-N-S/TiO2, and P-N-S/TiO2) were successfully prepared and tested in the photocatalytic removal of thiacloprid (THI) under UV-A, visible, and direct solar light irradiation. The physical-chemical properties of the prepared catalysts were analyzed by different characterization techniques, revealing that dopants are effectively incorporated into the anatase TiO2 lattice, resulting in a decrease of the energy band gap. The reduction of photoluminescence intensity indicates a lower combination rate and longer lifespan of photogenerated carriers of all doped samples in comparison with the un-doped TiO2. The doped photocatalysts not only significantly promote the photodegradation under UV-A light irradiation but also extend the optical response of TiO2 to visible light region, and consequently improve the visible light degradation of THI. Fe-N-P tri-doped TiO2 sample exhibits the highest THI photodegradation degree (64% under UV-A light, 29% under visible light and 73% under solar light).

Abstract (sommario):

Fe-doped TiO2nanotubes (Fe-TNTs) have been prepared by ultrasonic-assisted hydrothermal method. The structure and composition of the as-prepared TiO2nanotubes were characterized by transmission electron microscopy, X-ray diffraction, and UV-Visible absorption spectroscopy. Their photocatalytic activities were evaluated by the degradation of MO under visible light. The UV-visible absorption spectra of the Fe-TNT showed a red shift and an enhancement of the absorption in the visible region compared to the pure TNT. The Fe-TNTs were provided with good photocatalytic activities and photostability and under visible light irradiation, and the optimum molar ratio of Ti : Fe was found to be 100 : 1 in our experiments.

Abstract (sommario):

The carbon doped TiO2 nanoparticles with different amount of carbon content were prepared using starch as the carbon source. The physical properties of the as-prepared catalyst were determined using X-ray diffraction, transmission electron microscopy and UV-vis diffuse reflectance spectroscopy. The results showed that carbon was successfully doped into TiO2 and the optical response of TiO2 was shifted from UV to the visible light region. The photocatalytic activity of these catalysts was evaluated by the degradation of phenol under UV and visible light irradiation. C-doped TiO2 nanocomposites showed better photocatalytic activity than the undoped TiO2 nanoparticles. The degradation rate of phenol on C-doped TiO2 was higher than those of pure TiO2 under visible light. As the results, C-doped TiO2 possessed better absorption ability of visible light. The kinetic studies revealed that the degradation of phenol follows pseudo first order reaction relationship.

Abstract (sommario):

SUMMARY The aim of this study was to characterize the lenticular ultraviolet transmission of the Siberian hamster (Phodopus sungorus) and to probe the range of near-ultraviolet (UV-A, 315–400nm) and visible wavelengths (400–760nm) for modulating the photoperiodic regulation of its reproductive and immune systems. Ocular lenses from adult hamsters were found to transmit UV-A wavelengths at similar levels to visible wavelengths, with a short-wavelength cut-off of 300nm. Five separate studies compared the responses of juvenile male hamsters to long photoperiods (16h:8h L:D), short photoperiods (10h:14h L:D) and short photoperiods interrupted by an equal photon pulse of monochromatic light of 320, 340, 360, 500 or 725nm during the night. The results show that UV-A wavelengths at 320, 340 and 360nm can regulate both reproductive and immune short-photoperiod responses as effectively as visible monochromatic light at 500nm. In contrast, long-wavelength visible light at 725nm did not block the short-photoperiod responses. These results suggest that both wavelengths in the visible spectrum, together with UV-A wavelengths, contribute to hamster photoperiodism in natural habitats.

Abstract (sommario):

Abstract In current study UV light and visible light activated photocatalytic inactivation treatment was applied to the less commonly studied subjects, namely bacteriophages PRD1, T4 and their mixture. By using UV light irradiation and high efficiency P25 TiO2 photocatalyst powders it was demonstrated that individually and in mixture PRD1 bacteriophage is particularly vulnerable to the photocatalytic inactivation and in just approximately 20 min its infectivity is reduced by 100 %. As for the T4 bacteriophage, it has been reported that under UV irradiation T4 triggers self-repair and replication mechanisms therefore under same photocatalytic inactivation conditions infectivity reduction reaches just 60 %. Surprisingly, by studying visible light photocatalytic treatment efficiency of PRD1 and T4 bacteriophage mixture we identified that T4 bacteriophage potentially triggers the same self-repair and replication mechanism as it does under UV light. Moreover, by using two different types of visible light activated photocatalysts we determined that when efficiency of the used photocatalyst is too small the overall infectivity of the T4 bacteriophage can significantly surpass the corresponding property of the untreated control group.

Abstract (sommario):

The CVD diamond UV photodetector shows more than four orders of photoresponsivity discrimination between UV and visible light. Post-treatment on as-fabricated photodetector is essential for a good response to UV light and blindness to visible light. The CVD diamond X-ray detector shows linear dependence of photocurrent on X-ray intensity and high response speed. The mapping of charge collection efficiency on the whole sensing area of a CVD diamond alpha particle detector has been obtained using ion-beam-induced charge microscopy technique. Three peaks have been observed in the charge collection spectrum.

Abstract (sommario):

Abstract Climate change is altering light regimes in lakes, which should impact disease outbreaks, since sunlight can harm aquatic pathogens. However, some bacterial endospores are resistant to damage from light, even surviving exposure to UV-C. We examined the sensitivity of Pasteuria ramosa endospores, an aquatic parasite infecting Daphnia zooplankton, to biologically relevant wavelengths of light. Laboratory exposure to increasing intensities of UV-B, UV-A, and visible light significantly decreased P. ramosa infectivity, though there was no effect of spore exposure on parasitic castration of infected hosts. P. ramosa is more sensitive than its Daphnia host to damage by longer wavelength UV-A and visible light; this may enable Daphnia to seek an optimal light environment in the water column, where both UV-B damage and parasitism are minimal. Studies of pathogen light sensitivity help us to uncover factors controlling epidemics in lakes, which is especially important given that water transparency is decreasing in many lakes.

Abstract (sommario):

Phase transition of anatase nanoparticles into the phases TiO2-II and rutile under grinding was studied. The addition of ammonium carbamate to the reaction mixture inhibits the phase conversion and the cold welding of particles. The UV-visible absorption spectrum showed narrowing the band gap width after grinding with an ammonium carbamate additive resulting in shift of the light absorption of the ground sample towards the visible region. By EPR, intensive formation of OH•radical at irradiation of the sample with both UV (λ> 300 nm) and visible (λ> 435 nm) light was observed. High photocatalytic activity of the ground sample in visible light region was demonstrated also by measurement of kinetics of the photocatalytic decomposition of 4-chlorophenol.

Abstract (sommario):

A palladium (Pd) doped mesoporous titanium dioxide (TiO2) photocatalyst was used to produce hydrogen (H2) via water splitting under both near-UV and visible light. Experiments were carried out in the Photo-CREC Water-II Reactor (PCW-II) using a 0.25 wt% Pd-TiO2 photocatalyst, initial pH = 4 and 2.0 v/v% ethanol, as an organic scavenger. After 6 h of near-UV irradiation, this photocatalyst yielded 113 cm3 STP of hydrogen (H2). Furthermore, after 1 h of near-UV photoreduction followed by 5 h of visible light, the 0.25 wt% Pd-TiO2 photocatalyst yielded 5.25 cm3 STP of H2. The same photocatalyst, photoreduced for 24 h under near-UV and subsequently exposed to 5 h of visible light, yielded 29 cm3 STP of H2. It was observed that the promoted redox reactions led to the production of hydrogen and by-products such as methane, ethane, ethylene, acetaldehyde, carbon monoxide, carbon dioxide and hydrogen peroxide. These redox reactions could be modeled using an “in series-parallel” reaction network and Langmuir Hinshelwood based kinetics. The proposed rate equations were validated using statistical analysis for the experimental data and calculated kinetic parameters. Furthermore, Quantum yields (QYH•%) based on the H• produced were also established at promising levels: (a) 34.8% under near-UV light and 1.00 g L−1 photocatalyst concentration; (b) 8.8% under visible light and 0.15 g L−1. photocatalyst concentration following 24 h of near-UV.

Abstract (sommario):

Novel visible light photocatalytic graphitic carbon nitride/TiO2(g-C3N4/TiO2) composite samples were synthesized by heating mixtures of melamine and commercial TiO2(TO) at different weight ratios. The samples were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), photoluminescence spectroscopy (PL), Fourier transform infrared spectroscopy (FTIR), and UV-visible diffused reflectance spectroscopy (UV-vis DRS). Characterization confirms formation of nanocomposites of g-C3N4/TiO2. At the optimized precursor weight ratio (melamine:mTiO2=2.5), the samples exhibited highest adsorption capacity and visible light photocatalytic activity, measured by degradation of methylene blue (MB). Under visible light irradiation, the excited electrons on the surface of g-C3N4transfer easily to the conduction band (CB) of TiO2via the well-built heterojunction. The g-C3N4/TiO2nanocomposites exhibit enhanced visible light catalytic activity due to increased visible light adsorption and effective separation of photogenerated electron-hole pairs. These g-C3N4/TiO2nanocomposites could find broad applicability in environmental protection due to their excellent visible light photocatalytic property and facile, cost-effective preparation process.

Abstract (sommario):

In the present study, the objective was to probe the capacity of the Fe2O3/Bentonite/TiO2 (Fe2O3/B/TiO2) nanoparticles to act as a catalyst in degrading the reactive red 198 (RR198) dye and textile factory wastewater, utilizing irradiation with visible and UV light. The efficiency of this degradation was studied for a variety of experimental parameters by employing real samples of textile wastewater. After 60 min of reaction time, complete degradation of the target pollutant was visible using the synthesized catalyst, i.e., Fe2O3/B/TiO2, under UV light; the same effect was noted after 90 min under visible light. Further, the ease of separation and quick collection of the synthesized Fe2O3/B/TiO2 can result in keeping the photocatalytic efficiency high, as well as raising the reusability. The photocatalytic processes under UV and visible light were found capable of converting the non-biodegradable textile wastewater into biodegradable one. Besides, with the introduction of Daphnia manga, the toxicity of the effluent was examined. Through photocatalysis, utilizing both techniques, the dye toxicity in the solution was fully neutralized, and the intensity of toxicity of the textile effluent was lowered by around 70%. The conclusion drawn in this study showed that the synthesized catalyst displayed good efficiency in removing organic compounds from the textile effluents by both photocatalytic processes using UV and visible light.

In this study, nanocomposites were fabricated through the sol-gel technique. Structure, optical, and magnetic properties were analyzed using XRD, DRUV-Vis, FTIR, and VSM analysis. The XRD pattern revealed the anatase phase of TiO2 and the iron oxide formed was Fe3O4. UV-Vis spectroscopy showed the formation of absorption in the visible region in the presence of Ni doping. The nanocomposite had magnetic properties of 12.6 emu/g with paramagnetic type. TiO2 nanoparticles presented the percentage reduction of Ag ions with UV and Visible light of 82.65% and 21.43%, respectively, while Fe3O4/ TiO2-Ni with UV and Visible light were 80.93% and 90.72%, respectively.

Abstract (sommario):

Fluorescent materials emit light of higher wavelength, in case of illumination with light exhibiting lower wavelength. In many commercial applications, fluorescent materials transfer non-visible ultraviolet (UV) light into visible light. By this an additional color effect and higher visibility is reached. One typical field for application of fluorescence dyes is the textile area. Here, fluorescent textile products are manifold used and offered, e.g. for brightening effects, light effects and UV protection. With this background, the aim of the current study is the investigation of typical commercially available textile products with fluorescent properties. For this, four different polyester fiber-based materials of different coloration and purpose are selected for investigation. Investigations are performed by illumination under different illumination arrangements with UV light and visible light. CIE-Lab measurements are done. Further, scanning electronic microscopy (SEM) and Fourier Transform infrared (FT-IR) spectroscopy are used. Light emission and excitation of the samples is recorded by fluorescence spectroscopy. 2D fluorescence spectroscopy is performed. The chemical composition of the investigated textile samples is determined by using electron dispersive spectroscopy (EDS). For all investigated commercial textile products, the light emission during illumination with UV light is extraordinary strong. The color appearance can be enhanced strongly by this fluorescence effect. Beside the absorption of UV light by the present fluorescence dyes, also the presence of titanium dioxide supports an UV protective property of the textile samples. Finally, it can be concluded that fluorescent fiber materials are well established products for advanced and functional textiles. These materials can be even found in cost effective and everyday consumer products.
