dc.descriptionWe prepared a W/WO3/TiO2 bicomposite photoanode by simple electrochemical anodization of W foil, followed by cathodic electrodeposition of TiO2 and annealing at 450 C for 30 min. This photoanode shows good photoactivity under irradiation with UV and visible light. In optimized conditions, it promotes complete photoelectrocatalytic oxidation of 3.33 × 10-5 mol L-1 basic red 51 solution (which is used in hair dye) at 0.1 mol L-1 Na2SO4, pH 2.0, under a current density of 1.25 mA cm-2 and 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. © 2013 Elsevier Ltd. All rights reserved.
