摘要
The application of electrochemically enhanced photocatalysis in air treatment using a Nafion-based photoelectrochemical cell and TiO2/WO3 photoanodes for organic vapor photooxidation under both UV and visible light irradiation is briefly presented. In that direction, the obtained results regarding the preparation and characterization of the TiO2/WO3 photoanodes with enhanced photocatalytic activity are reviewed. Particular emphasis is given in the comparison of the photocatalytic behavior of bilayer TiO2/WO3 coatings, electrosynthesized on stainless steel mesh and powder C + mixed (WO3 + TiO2) photoanodes. The advantages of using a high surface area C + mixed (WO3 + TiO2) powder catalysts as photoanodes against their plain TiO2 + C and WO3 + C analogues are discussed.
