Abstract:
Titanium dioxides were synthesized from two different titanium salts, which contained chlorine and sulfur respectively. Titanium dioxide prepared from TiCi4 and had a particle size of ca. 20nm and its phase transition from anatase to rutile stated at 500°C. Titanium dioxide from TiOSO4 had a particle size of ca. 50nm and retained its anatase and sperit structure until 700°C by calcination. For the photocatalytic evaluation of these titanium dioxides, photocatlytic oxidation of organic model pollutant, humic acid, have been conducted. UV absorbance decrease by titanium dioxides prepared from both from TiCi4 and TiOSO4 at room temperature showed very similar results, compared to titanium dioxide prepared from TiCi4 at higher temperature.

Abstract:
Titanium dioxide (Titania; TiO2) is one of the most widely used metal oxide semiconductor in the field of photocatalysis for removal of pollutants. It has been noted that titanium dioxide is a research friendly material as its physico-chemical and catalytic properties can be easily altered as per specific application. Since many years, researchers have tried to modify the properties of titanium dioxide by means of doping with metals and non-metals to improve its performance for photocatalytic degradation (PCD) applications. The doping of various metal ions like Ag, Ni, Co, Au, Cu, V, Ru, Fe, La, Pt, Cr, Ce, etc. in titanium dioxide have been found to be influencing the band gap, surface area, particle size, thermal property, etc. and therefore the photocatalytic activity in PCD. Moreover, photocatalytic activity of doped titanium dioxide has been observed in visible light range (i.e., at wavelength >400 nm). In this review, different synthesis route for doping of metal ions in titanium dioxide have been emphasised. The effect of metal dopant on the structural, textural and photocatalytic properties of titanium dioxide has been reviewed.

Abstract:
The paper overviews the process of thermolysis of fire-retardants based on melamine, ammonium polyphosphate and pentaerythtritol and containing titanium dioxide of different trademarks. The role of titanium dioxide as a component of fire-retardants is revised. Titanium dioxide was perceived only as white pigment, but this paper states that the properties of a charred layer forming from an intumescent coating depend on the properties of titanium dioxide's species, such as surface treatment and crystalline structure. This statement is proven by using thermal analysis of intumescents with different titanium dioxide's trademarks; it shows that rutile titanium dioxide helps forming a charred layer with the highest thermal stability thus fire retardant efficiency grows up. It means that the knowledge of processes which occur in intumescents based on primary products with different qualities helps to create fire-protective compositions which will perform more reliable in case of fire.

Abstract:
Titanium dioxide has attracted worldwide attention due to its prominent photocatalytic activity. It is generally accepted that nanoparticulate titanium dioxide with pure anatase structure exhibits high reactivity. Sol-gel is a simple and cost-effective technique capable of synthesizing anatase-phase titanium dioxide with particle sizes in nanometer range. This research aimed at examining effects of ageing periods on compositions and sizes of titanium dioxide synthesized by sol-gel technique. Experimental results revealed that prolonged ageing period demoted formation of anatase phase. Pure anatase phase was observed at ageing period of 1 day, while both anatase and rutile phases were observed at ageing periods of 4 and 7 days. The results also indicated that particle sizes decreased as the ageing periods increased. Nanoparticulate titanium dioxides with average sizes of 71.5, 50.4, and 29.7 nanometer were observed at ageing periods of 1, 4, and 7 days, respectively.

Abstract:
Titanium dioxide, first manufactured a century ago, is significant in industry due to its chemical inertness, low cost, and availability. The white mineral has a wide range of applications in photocatalysis, in the pharmaceutical industry, and in food processing sectors. Its practical uses stem from its dual feature to act as both a semiconductor and light scatterer. Optical performance is therefore of relevance in understanding how titanium dioxide impacts these industries. Recent breakthroughs are summarised herein, focusing on whether restructuring the surface properties of titanium dioxide either enhances or inhibits its reactivity, depending on the required application. Its recent exposure as a potential carcinogen to humans has been linked to controversies around titanium dioxide’s toxicity; this is discussed by illustrating discrepancies between experimental protocols of toxicity assays and their results. In all, it is important to review the latest achievements in fast-growing industries where titanium dioxide prevails, while keeping in mind insights into its disputed toxicity.

Abstract:
Dense and mesoporous titanium dioxide films have been obtained on titanium substrate by means of thermal oxidation, hydrolysis of polybutyltitanate, deposition of titanium dioxide sol, ultrasonic treatment and anodic oxidation and characterized by scanning electron microscopy, transmission electron microscopy and Raman spectroscopy. Electrochemical activity of titanium dioxide films, initial and modified by gold nanoparticles, in oxygen reduction reaction (ORR) in alkaline medium has been studied by cyclic voltammetry. It has been demonstrated that the efficiency of the dense and mesoporous titanium dioxide films in ORR is determined by their morphology, structure and pore ordering degree. Modification of titanium dioxide films by gold nanoparticles results in the decrease in overpotential of the ORR. It has been found that the electrodes consisted of highly ordered layers of titania nanotubes with deposited gold nanoparticles demonstrate sufficiently higher electrocatalytic activity toward the oxygen electroreduction in comparison with TiO2/Au systems based on dense films and mesoporous films with disordered pore structure. Features of electrochemical behavior of TiO2/Au (nanotubes/nanoparticles) system are explained by the peculiarities of electron transport to the electrode surface and structure of space charge layer in the mesoporous oxide film.

Abstract:
A ultaviolet–visible light responded photocatalytic nanocomposite, silver/silver bromide/titanium dioxide, supported on graphene oxide (GO; silver/silver bromide/titanium dioxide/GO) was fabricated via a layer intercalation method using n-butylamine, cetyltrimethyl ammonium bromide, titanium dioxide and silver/silver bromide-intercalated GO successively. The resultant silver/silver bromide/titanium dioxide/GO exhibited much stronger visible light absorption and enhanced photocatalytic efficiency than titanium dioxide/GO and titanium dioxide. Furthermore, the degradation efficiency of silver/silver bromide/titanium dioxide/GO was improved when irradiated under light without the ultaviolet cut filter. The apparent degradation rate constants, k, for silver/silver bromide/titanium dioxide/GO, titanium dioxide/GO and titanium dioxide are 0.5192, 0.2273 and 0.0627 h−1. A possible photocatalytic degradation mechanism for degradation of 4-chlorophenol by silver/silver bromide/titanium dioxide/GO under irradiation with/without the ultaviolet cut filter was proposed. The factors including the visible light response from silver bromide, surface plasmon ‘hot’ electron effect from silver nanoparticles and efficient electron transfer among silver, silver bromide, titanium dioxide and GO are contributed to enhance the photocatalytic activity under visible light irradiation, while the additional factor of ultaviolet light response from titanium dioxide plays an important role under light irradiation without the ultaviolet cut filter. The resultant silver/silver bromide/titanium dioxide/GO possessed a good photochemical stability and reusability.

Abstract:
Four specific studies are presented in this thesis, regarding the high-pressure phases of the three compounds. ZrO$\sb2$ was studied at pressures of up to 73 GPa using energy dispersive X-ray (EDX) diffraction techniques. The quenched phase was analysed using angle dispersive X-ray (ADX) diffraction with imaging plates, and was identified as having a cotunnite-type structure (space group Pnma) by Rietveld refinement. HfO$\sb2$ was also studied to 72 GPa using EDX diffraction measurements, and its quenched phase was also identified as having a cotunnite-type structure, based on the simularities of its EDX and Raman spectra with those of the quenched phase of ZrO$\sb2$. TiO$\sb2$ was involved in two separate studies. The first is a Raman spectroscopic study up to 73 GPa, starting with anatase. Some EDX diffraction measurements were also taken to pressures up to 105 GPa. Additionally, EDX diffraction measurements of TiO$\sb2$ up to 28 GPa were taken to determine the equations of state of its high-pressure phases, starting with anatase and furtile at atmospheric pressure.

Abstract:
Titanium dioxide, "titania" is used for a wide range of everyday applications, such as in sunblocks, paints, paper, and some plastics. For these uses it is necessary to reduce the photoactivity of the titania for either product quality or consumer safety. Titanium dioxide also finds application in the field of photocatalysis for pollution abatement and in this instance a high photoactivity is desirable. This thesis describes the development and characterisation of two main strategies intended to reduce titania photoactivity: the addition of iron dopants to suppress the number of surface radicals (Chapters 3 and 4), and the addition of an organic coating to the titania to scavenge the radicals (Chapters 5 and 6). The titania was iron doped in two ways, either only on the surface, or in the lattice and on the surface (shown by Electron Paramagnetic Resonance "EPW' spectra). The effect of several novel organic coatings on the photoactivity was tested: a phosphate, an organophosphate based coating and an organosilane. Two types of titanium dioxide were modified, a rutile sample used in commercial sunblocks and Degussa P25, a titania commonly used in research. The efficiencies of these strategies were tested by several methods to determine the effect of solution medium on the photoactivity. A new technique of 2-nitrophenol degradation was developed to measured photoactivity in aqueous solutions and compared with the well characterised technique of 2-propanol oxidation. In addition, a test based on salicylic acid degradation was developed and shown to measure the photoactivity by direct hole oxidation. Infra red spectroscopy and surface area determination were used to analyse how the coatings formed on the titania surface. IR spectra show that the headgroups bond to the surface and so the coatings are hydrophobic. Careful analysis showed that organosilanes form on the surface as crosslinked polymers. Lastly, work on 4-nitrophenol degradation carried out under my guidance complements earlier work on 2-nitrophenol degradation to show that UV absorption by the solution affects the measured kinetics of photocatalytic degradation.

Abstract:
Titanium dioxide, TiO2, has potential applications as a photoelectrode for photoelectrochemical generation of hydrogen by splitting water using solar energy and as a photocatalyst for water purification. This study is part of the UNSW research program to process TiO2-based oxide semiconductors as high-performance photoelectrodes and photocatalysts. This study investigates the effect of defect disorder on semiconducting properties of polycrystalline TiO2. This study involved the processing of high-purity polycrystalline TiO2 and determination of its semiconducting properties through measurement of electrical conductivity and thermoelectric power at elevated temperatures (1073-1323K) in controlled oxygen activities [1x10-13 Pa < p(O2) < 75 kPa]. The study included two types of experiments: Determination of electrical properties under conditions of gas/solid equilibrium. The data obtained was used to derive defect disorder and related semiconducting properties Monitoring of electrical properties during equilibration. This data was used to determine the chemical diffusion coefficient. The data obtained under equilibrium conditions indicates that oxygen may be used as a dopant to impose controlled semiconducting properties. In reduced conditions TiO2 is an n-type semiconductor and under oxidizing conditions TiO2 is a p-type semiconductor. The n-type behaviour is associated with oxygen vacancies as the predominant defects and titanium interstitials as the minority defects. The p-type behaviour is closely related to titanium vacancies that are formed during prolonged oxidation. Charge transport at elevated temperature was shown to involve substantial contribution from ions. Analysis of electrical properties enabled determination of several defect-related quantities including the activation enthalpy for oxygen vacancy formation, and the activation energy of the electrical conductivity components related to electrons, holes and ions. The kinetic data obtained during gas/solid equilibration enabled determination of the chemical diffusion coefficient which exhibited a complex dependence on nonstoichiometry. In addition, prolonged oxidation showed that equilibration occurred in two kinetic regimes. One for highly mobile oxygen vacancies and titanium interstitials which quickly reached an ??operational equilibrium?? within hours and another slow kinetic regime for equilibration of titanium vacancies over many thousand hours. The determined chemical diffusion coefficient data may be used to select the processing conditions required to impose uniform concentration of defects within a TiO2.

Abstract:
Despite extensive preventative efforts, the problem of controlling infections associated with biomedical materials persists. Bacteria tend to colonize on biocompatible materials and form biofilms; thus, novel biomaterials with antibacterial properties are of great interest. In this thesis, titanium dioxide (TiO2)-associated photocatalysis under ultraviolet (UV) irradiation was investigated as a strategy for developing bioactivity and antibacterial properties on biomaterials. Although much of the work was specifically directed towards dental materials, the results presented are applicable to a wide range of biomaterial applications. Most of the experimental work in the thesis was based on a resin-TiO2 nanocomposite that was prepared by adding 20 wt% TiO2 nanoparticles to a resin-based polymer material. Tests showed that the addition of the nanoparticles endowed the adhesive material with photocatalytic activity without affecting the functional bonding strength. Subsequent studies indicated a number of additional beneficial properties associated with the nanocomposite that appear promising for biomaterial applications. For example, irradiation with UV light induced bioactivity on the otherwise non-bioactive nanocomposite; this was indicated by hydroxyapatite formation on the surface following soaking in Dulbecco’s phosphate-buffered saline. Under UV irradiation, the resin-TiO2 nanocomposite provided effective antibacterial action against both planktonic and biofilm bacteria. UV irradiation of the nanocomposite also provided a prolonged antibacterial effect that continued after removal of the UV light source. UV treatment also reduced bacterial adhesion to the resin-TiO2 surface. The mechanisms involved in the antibacterial effects of TiO2 photocatalysis were studied by investigating the specific contributions of the photocatalytic reaction products (the reactive oxygen species) and their disinfection kinetics. Methods of improving the viability analysis of bacteria subjected to photocatalysis were also developed.

Abstract:
In the present thesis we propose the development of hybrid polymer titanium dioxide (TiO2) nanoparticles for use in biomedical applications. TiO2 exhibits high biocompatibility in the dark however, upon illumination in aqueous media with near UV light it produces an array of reactive oxygen species (ROS) which have the capability to induce death in neighbouring cells. The process of inducing cell death using a photosensitive material which produces ROS is known as photodynamic therapy (PDT) and is used to treat a wide range of maladies from psoriasis to cancer.We have demonstrated the ability to produce anatase nanoparticles with high control over their resulting size through a novel water mediated sol-gel synthetic method in benzyl alcohol, using either Ti(OnPr)4, Ti(OnBu)4 or Ti(OiPr)4 as the metal precursor. Through dynamic light scattering (DLS) analysis we have shown that the mechanism of nanoparticle growth appears to proceed through the agglomeration of primary nanoparticles formed instantly upon adding the reagents together. After synthesis the nanoparticles could be easily redispersed in aqueous media at pH2 with any further agglomeration being controlled by the parent alkoxide.After synthesis the nanoparticles were coated with PEG, conjugated to either a catechol or phosphate as ligand, in order to stabilise the nanoparticles at neutral pH. Uncoated nanoparticles exhibited good photoactive capability in the photooxidation of methylene blue. However, on coating with catechols the photoactivity of the nanoparticles was abolished. Coating with phosph(on)ates on the other hand preserved or even enhanced the photoactivity which makes this system promising for in vivo applications.At the same time this thesis also reports preliminary investigations on the use of TiO2 embedded into the walls of model drug loaded poly electrolyte multilayer microspheres for UV triggered delivery applications.

Abstract:
Titanium Oxide film produced by reactive electron beam evaporation typically have a columnar microstructure1,2,3,4,5. The optical performance of such films often varies due to the absorption of water vapor. Since water is transparent in the visible region it might be expected that the changes there would be reasonably free of absorption. We report here two methods that have been investigated where significant changes in absorption occur. When the environmental changes cab be reversed, the absorption is also reversible.

Abstract:
This project focused on the evaluation of the influence of nanoadditives on the hydration kinetics, mechanical properties, and durability of concretes with and without supplementary cementitious materials (SCMs). The types of nanomaterials used in the course of this study included nano-titanium dioxide (nano-TiO2) and two forms of nanosilica. A series of experimental tasks, including fabrication, curing, and conditioning of specimens, microstructure analysis, mechanical strength testing, and durability testing were conducted in the laboratory. Based on experimental results, it can be concluded that the addition of nanoparticles can accelerate the early-age hydration process of cementitious pastes, especially those containing fly ash and cured at low temperatures. Both the compressive and flexural strength of mortars and concretes were also enhanced by the addition of nanoparticles. In addition, incorporation of nanoparticles reduced the total amount and connectivity of pores present in concretes. That resulted in lowering the water permeability of concretes, regardless of the cementitious systems and curing temperatures used. The resistance of concretes to freeze-thaw cycles and scaling was also improved by the addition of nanoparticles, especially those containing fly ash. However, an excess of nanoparticles additions may reduce the scaling resistance of concretes.
