Abstract:
Photoelectrocatalysis is a hybrid photon/electron-driven process that benefits from the synergistic effects of both processes to enhance and stabilize the generation of disinfecting oxidants. Photoelectrocatalysis is an easy to operate technology that can be scaled-up or scaled-down for various water treatment applications as low-cost decentralized systems. This review article describes the fundamentals of photoelectrocatalysis, applied to water disinfection to ensure access to clean water for all as a sustainable development goal. Advances in reactor engineering design that integrate light-delivery and electrochemical system requirements are presented, with a description of photo-electrode material advances, including doping, nano-decoration, and nanostructure control. Disinfection and cell inactivation are described using different model microorganisms such as E. coli, Mycobacteria, Legionella, etc., as well the fungus Candida parapsilosis, with relevant figures of merit. The key advances in the elucidation of bacterial inactivation mechanisms by photoelectrocatalytic treatments are presented and knowledge gaps identified. Finally, prospects and further research needs are outlined, to define the pathway towards the future of photoelectrocatalytic disinfection technologies.

Abstract:
Multiple discs coated with hierarchically-organized TiO2 anatase nanotubes served as photoelectrodes in a novel annular photoelectrocatalytic reactor. Electrochemical characterization showed light irradiation enhanced the current response due to photogeneration of charge carriers. The pharmaceutical acetaminophen was used as a representative water micropollutant. The photoelectrocatalysis pseudo-first-order rate constant for acetaminophen was seven orders of magnitude greater than electrocatalytic treatment. Compared against photocatalysis alone, our photoelectrocatalytic reactor at <8 V reduced by two fold, the electric energy per order (EEO; kWh m−3 order−1 for 90% pollutant degradation). Applying a cell potential higher than 8 V detrimentally increased EEO. Acetaminophen was degraded across a range of initial concentrations, but absorbance at higher concentration diminished photon transport, resulting in higher EEO. Extended photoelectrocatalytic reactor operation degraded acetaminophen, which was accompanied by 53% mineralization based upon total organic carbon measurements. This proof of concept for our photoelectrocatalytic reactor demonstrated a strategy to increase photo-active surface area in annular reactors.

Abstract:
Photocatalytic and photoelectrocatalytic degradation of methyl violet dye using Graphite/PbTiO3 composites has been conducted. The purposes of this research were to examine photocatalytic and photoelectrocatalytic degradation of methyl violet using Graphite/PbTiO3 composite. Synthesis of Graphite/PbTiO3 composite was successfully performed via sol-gel method by mixing graphite powder, titanium tetra isopropoxide precursor solution (TTIP) and Pb(NO3)2. The Graphite/PbTiO3 composites were characterized using X-Ray Diffraction (XRD), Fourier Transform-Infra Red (FT-IR), and Scanning Electron Microscopy (SEM). The XRD diffractogram and IR spectrum of Graphite/PbTiO3 composite revealed all characteristic peak of graphite and PbTiO3. Photocatalytic degradation process showed that Graphite/PbTiO3 composite with ratio 1/1 decreased concentrations of methyl violet up to 92.20 %. While photoelectrocatalytic degradation processed for 30 minutes at neutral pH and 10 V voltage degraded the methyl violet until 94 %. However, the photoelectrocatalysis is still not significance to improve methyl violet degradation compared with photocatalysis. Copyright © 2018 BCREC Group.

Abstract:
The photoelectrocatalytic (PEC) oxidation degradation of landfill leachate rejected by reverse osmosis (RO) using a Cu/N codoped TiO2/Ti photoelectrode was kinetically investigated in terms of COD concentration. The key factors affecting the reaction rate of PEC oxidation and the removal efficiency of COD concentration were studied, including the COD concentration of landfill leachate, potential bias applied, pH value of landfill leachate, and the reaction temperature of photoelectrocatalytic reactor. The apparent kinetic model was applied to describe the photoelectrocatalysis reaction. The results showed that the kinetic equation for photoelectrocatalytic oxidation of landfill leachate was fitting well with the experimental data (R2=0.967~0.998), with average activation energyEa=6.35 × 104 J·mol−1. It was found that there was an optimal bias voltage of 20 V and low pH value was favorable for COD removal in landfill leachate. The reaction order of initial COD concentration (1.326) is higher than that of potential bias (1.102) and pH value (0.074), which indicates that the reaction rate can be controlled efficiently through adjusted initial concentration. The experiments demonstrated that potential bias would approach its statured value with increasing potential bias.

Abstract:
The photoelectrocatalytic performance of benzoic acid on TiO2nanotube array electrodes was investigated. A thin-cell was used to discuss the effect of the bias voltage, illumination intensity, and electrolyte concentration on the photoelectrocatalytic degradation efficiency of benzoic acid. The photogenerated current-time (I-t) profiles were found to be related to the adsorption and the degradation process. The relationship between the initial concentration and the photocurrent peaks (I0ph) fits the Langmuir-type adsorption model, thus confirming that the adsorption of benzoic acid on TiO2nanotube arrays (TNAs) was single monolayer adsorption. At low concentrations, theI-tprofiles simply decay after the initial transient peak due to the sufficient holes on the TNAs which would oxidize the benzoic acid quickly. However, theI-tprofiles varied with increasing benzoic acid concentrations because the rate of diffusion in the bulk solution and the degradation of the intermediate products affect the photoelectrocatalysis on the electrode surface.

Abstract:
Générer des carburants solaires, comme l’hydrogène via la photoélectrolyse de l’eau, est une stratégie à explorer pour notre futur énergétique. Pour éviter l’emploi du platine en tant que catalyseur de production d’hydrogène, des métaux abondants peuvent être utilisés. Au laboratoire, le complexe diimine-dioxime de cobalt, catalyseur moléculaire de réduction des protons, a pu être immobilisé pour créer une cathode produisant de manière stable de l’hydrogène en milieu aqueux. Dans ces travaux, nous avons étudié l’introduction du catalyseur dans des dispositifs photoélectrocatalytiques. Différentes conditions opératoires dans l’eau, solvant de choix, ont été examinées. Le complexe se dégrade s’il est en solution mais son activité est maintenue, même en présence d’oxygène, s’il est supporté sur électrode. Cette électrode a ainsi pu être intégrée en cellule tandem. De nouveaux dérivés du complexe ont aussi été développés pour l’attachement sur oxydes transparents conducteurs. Un dérivé a été co-immobilisé avec des photosensibilisateurs sur une surface de NiO, oxyde de type p. Les photocathodes co-greffées obtenues ont été caractérisées par un ensemble de techniques analytiques et ont démontré la production d’hydrogène en conditions photoélectrocatalytiques. Des entités colorant-catalyseur pouvant s’ancrer sur surface ont également été synthétisées et ouvrent de nouvelles voies pour élaborer des photocathodes moléculaires
Solar fuels generated from the light-induced splitting of water into H2 and O2 is an appealing strategy for securing future energy. The use of platinum for catalyzing hydrogen evolution may be bypassed with earth-abundant catalysts. In a previous study, our lab realized the immobilization of a proton reduction catalyst, the cobalt diimine-dioxime molecular complex, within a cathode material steadily evolving H2 from fully aqueous media. In this work, we report on the implementation of this catalyst into light-driven devices. Operating conditions in the solvent of interest, water, were screened. The molecular catalyst degrades when free in solution, but retains activity when supported on an electrode, even in the presence of O2, and could thus be integrated into a tandem cell. Further on, new derivatives of the catalyst were developed for the attachment onto transparent conducting oxides. Co-grafted photocathodes were constructed by anchoring a functionalized catalyst along with photosensitizers onto p-type NiO. These architectures were checked by a whole set of analytical techniques and light-driven catalytic hydrogen evolution was achieved by photocathodes assessed under device-related photoelectrochemical conditions. Immobilizable dye-catalyst dyads were also successfully synthetized as alternative derivatives and open up new possibilities to develop molecular photocathodes

La photoelectrocatalyse de l'eau par rayonnement solaire est une solution communément proposée pour la production propre d'hydrogène. En termes de rendement solaire-à-hydrogène, un tandem dual photosystème est accepté comme la configuration plus efficace concernant les cellules photoelectrocatalytique pour la dissociation de l'eau. Ce travail s'intéresse au trioxyde de tungstène (WO3) et au bismuth vanadate (BiVO4) sous la forme de photoanodes type n en couches minces pour la complétion d'oxydation de l'eau dans la demi-réaction pour la dissociation complète de l'eau dans une cellule tandem dual photosystème photoelectrocatalytique. Ces couches minces sont fabriquées par des méthodes robustes, économiques, et extensibles de sol-gel dip coating, et caractérisées par différentes techniques pour vérifier leurs caractéristiques physiques et leur performance photoelectrochimique. WO3 et BiVO4 sont optimises par nanostructuration, modification des couches interfaciales, et addition des co-catalyseurs de surface pour améliorer les performances et la stabilité, respectivement dans des conditions acides et neutres. Ces matériaux sont couples avec une photocathode de type p en oxyde de cuivre (II) pour compléter la réaction de dissociation de l'eau. La cellule photoelectrocatalytique ainsi construite est inspirée par la littérature concernant les systèmes innovateurs de tandem dual photosystèmes. Ce travail aboutit à l'une des seules cellules de dissociation de l'eau par photoelectrocatalyse à base des oxydes de métaux, fabriquée via des techniques faciles et économiques. L'efficacité de la production solaire-à-hydrogène est de 0.01%, et applied-bias-to-photon efficacité de 0.06%
Solar water splitting by photoelectrocatalysis is a proposed long term solution for the production of renewable hydrogen. A wired dual photosystem photoelectrocatalytic cell is thermodynamically considered to possess the highest attainable solar-to-hydrogen efficiency. To realize a photoelectrocatalytic water splitting cell for practical application, facile fabrication methods and abundant low cost materials are essential. This research investigates tungsten trioxide (WO3) and bismuth vanadate (BiVO4) as thin film n-photoanodes to complete the oxygen evolution half reaction for water splitting application in a tandem dual photosystem photoeletrocatalyic water splitting cell. These thin films are fabricated by low cost, robust, scalable, sol-gel dip coating methods and characterized by several techniques to verify the physical characteristics and photochemical performance. WO3 and BiVO4 are optimized by nanostructuration, interfacial surface modification, and addition of surface co-catalysts to increase performance and stability in acidic and neutral conditions, respectively. These materials are coupled with a copper (II) oxide p-photocathode to drive the hydrogen evolution reaction in a photoelectrocatalyic cell to complete the water splitting reaction. The photoelectrocatalytic cell constructed is inspired by previous literature reports encompassing an innovative tandem dual photosystem approach. As a result, this research reports one of the only entirely metal oxide based photoelectrocatalytic water splitting cells, fabricated by inexpensive, unexcessive techniques, resulting in a solar-to-hydrogen efficiency of 0.01% and an applied bias to photon efficiency of 0.06%

Abstract:
Solar energy conversion and storage into hydrogen is a valuable approach to capture the energy that is freely available from sunlight and to turn it into a clean fuel. Photoelectrochemical (PEC) water splitting through the dual-absorber tandem cell technology has emerged as a promising strategy to this aim. The work conducted in the frame of this PhD thesis aimed at playing a part in the development and optimization of efficient oxide-based semiconductor photoanodes for water oxidation, which is the kinetic bottleneck of the overall PEC water splitting process. Photoanodes based on films of absorbing materials were successfully synthesized with a high optical transparency as important requirement for maximizing the solar energy conversion efficiency of the final tandem cell device. Subsequently, their intrinsic properties as single photoabsorber photoanodes were largely improved, on the basis of the results obtained through comprehensive PEC studies in parallel with thorough structural, morphological, and spectroscopic investigations. The attention was focused on three different classes of promising ternary metal oxides, able to absorb a large portion of the solar spectrum, namely i) BiVO4 (bandgap Eg = 2.4 eV), known for its excellent solar light to hydrogen conversion efficiency, ii) the copper tungstate-based materials CuWO4 (Eg = 2.3 eV) and CuW(1-x)Mo(x)O4 (Eg = 2.0 eV), ideal to be employed as visible-light active alternative to WO3, and iii) ZnFe2O4 (Eg = 2.0 eV) belonging to the spinel ferrites class, possessing excellent photothermal and chemical stability. Specifically, BiVO4 was studied either as a visible light sensitizer towards TiO2 or as a single photoanode material to focus on the identification and improvement of its intrinsically poor electron transport and interfacial transfer properties. In the first case, the TiO2/BiVO4 heterojunction system was proved to be effective in producing highly reductive electrons, suitable for overall water splitting, through TiO2 sensitization towards visible light. This, together with the counterintuitive mechanism at the basis of the observed impressive functionality, was effectively disclosed through combined PEC and photocatalytic reduction test studies. The multifaceted role of Mo6+ doping onto both the bulk and surface properties of BiVO4 films was also revealed through an in-depth PEC and impedance spectroscopy study. By improving either the bulk conductivity or the interfacial charge transfer of optimized Mo6+ doped BiVO4 photoanodes a conspicuous enhancement was attained of their photoactivity towards water oxidation with respect to the pure material. The presence of intra-gap states in CuWO4, acting as electron traps and thus being responsible for a severe internal charge recombination, was verified by means of the first ultrafast transient absorption study performed with this material, in combination with both an electrochemical and a photochromic characterization. This issue, which strongly limits the PEC performance of CuWO4 photoanodes, was addressed by adopting a 50% Mo for W substitution resulting in CuW0.5Mo0.5O4 photoanodes, exhibiting not only a greatly extended visible light-induced photoactivity compared to the pure material, as a result of enhanced absorption, but also a considerably improved charge separation. All these factors contributed to the much better PEC performance attained with respect to CuWO4 electrodes. This study was finalized by the identification of a suitable hole scavenger species for copper tungstate-based materials, able to ensure enhanced photocurrent generation compared to pure water oxidation while minimizing dark currents. Finally, in the frame of my seven months stage in Prof. Sivula’s group at the EPFL in Lausanne, a thorough study was performed on the impact that several parameters, such as the annealing temperature, the film thickness and the creation of oxygen vacancies through a reductive treatment in hydrogen atmosphere, have on the PEC performance of ZnFe2O4 photoanodes. The verified synergism between the higher crystallinity of the films subjected to a high-temperature annealing treatment and the hydrogenation efficiency, which proved effective in optimizing charge separation in the thicker photoactive layers, allowed one to maximize the performance of ZnFe2O4 electrodes for water oxidation. This study also shed light onto the strict correlation occurring between structural parameters, i.e. the film crystallinity and the spinel inversion degree, and the resulting PEC performance, which proved to be in turn controlled by the film morphology.

Thesis advisor: Udayan Mohanty
Among the existing strategies to direct solar energy harvesting and storage, solar fuel production by photoelectrocatalysis promises a comparatively simple, low-cost route. The science behind this process is straightforward: stable semiconductors absorb sunlight and use the energy to excite charges, which then drive redox reactions at the surface. Careful studies of the photoelectrode surface provide important considerations in building a high-performance photoelectrode. Specifically, I focused on controlling the surface band alignment of Cu2O photocathode|water for hydrogen evolution reaction. A ZnS buried heterojunction is formed to improve the photovoltage. Then I focused on understanding the influence of chemical species on surface kinetics and energetics for water oxidation reaction. Two hematite photoanodes with preferably exposed {001} and {012} facets were examined. Further, I systematically studied three different types of surfaces, bare hematite, hematite with a heterogenized Ir water oxidation catalyst (WOC), and a heterogeneous IrOx WOC. While both WOCs improve the performance of hematite by a large margin, their working mechanisms are found to be fundamentally different. I also focused on utilizing surface photoexcited species to control product selectivity. Selective CO production by photoelectrochemical methane oxidation is successfully demonstrated. Detailed experimental investigations revealed that a synergistic effect by adjacent Ti3+ sites is the key to CO formation

Abstract:
The thesis project is focused on the synthesis and characterization of nanostructured bismuth ferrite, BiFeO3 (BFO), thin films with enhanced photoelectrocatalytic properties. Photoelectrocatalytic materials are semiconductors that are able to catalyze water splitting processes or other reactions under sunlight irradiation. They can, through the absorption of photons, create electron/hole pairs which can be exploited to carry out electrochemical reactions. BFO is a very promising perovskite-type material with an optical band gap that fits well with the sunlight irradiation in the visible region. Since most of the conventional photocatalyst like TiO2 is limited by a wide band gap and a UV light absorption, the BFO material is an interesting visible light driven photoactive material for solar energy conversion. The main disadvantages of such material are poor efficiency and high variability in the photoelectrocatalytic performance. BFO’s performance depends on structure, defects, phase, electronic properties, which are directly connected with the synthetic methodology. In this thesis a sol-gel synthesis has been optimized in order to prepare highly reproducible thin films, that could be directly applied to a device, with modified structure and improved photoelectrocatalytic performance. Moreover, in order to achieve sensitization in the Near Infrared Region where pure BFO is not active, a composite nanomaterial has been developed. Previously prepared nanoparticles with peculiar optical properties have been dispersed in a BFO matrix and the optical and structural characterization have been carried out to correlate the enhancement of photoelectrocatalytic properties with the modification caused by the nanoparticles doping.
