In this paper, highly efficient and stable CuO/ZnO nanowire (CuO/ZnO-nw) based photocathode was fabricated using a facile and scalable technique for application in photoelectrochemical water splitting. Electro-deposition of Cu film on FTO glass followed by a subsequent chemical oxidation and dip-coa...
