Abstract
We prepared a W/WO3/TiO2bicomposite photoanode by simple electrochemical anodization of W foil, followed by cathodic electrodeposition of TiO2and annealing at 450°C for 30min. This photoanode shows good photoactivity under irradiation with UV and visible light. In optimized conditions, it promotes complete photoelectrocatalytic oxidation of 3.33×10-5molL-1basic red 51 solution (which is used in hair dye) at 0.1molL-1Na2SO4, pH 2.0, under a current density of 1.25mAcm-2and ultraviolet and visible radiation–total organic carbon removal is 94 and 88%, respectively. This effect paves the way for the sustainable solar-assisted remediation of water bodies contaminated with organic components of hair dyes.
