Towards visible light driven photoelectrocatalysis for water treatment: Application of a FTO/BiVO₄/Ag₂S heterojunction anode for the removal of emerging pharmaceutical pollutants.

ABSTRACT: Pharmaceuticals have been classified as emerging water pollutants which are recalcitrant in nature. In the quest to find a suitable technique in removing them from contaminated water, photoelectrocatalytic oxidation method has attracted much attention in recent years. This report examined the feasibility of degrading ciprofloxacin and sulfamethoxazole through photoelectrocatalytic oxidation using FTO-BiVO₄/Ag₂S with p-n heterojunction as anode. BiVO₄/Ag₂S was prepared through electrodeposition and successive ionic layer adsorption/reaction on FTO glass. Structural and morphological studies using XRD, SEM, EDS and diffusive reflectance UV-Vis confirmed the successful construction of p-n heterojunction of BiVO₄/Ag₂S. Electroch
