Photoelectrochemical Water Oxidation

Intensive attention has been currently focused on the discovery of semiconductor and proficient cocatalysts for eventual applications to the photoelectrochemical water splitting system. A W-Mo-doped BiVO4semiconductor was prepared by the surfactant-assisted thermal decomposition method on a fluorine-doped tin oxide conductive film. The W-Mo-doped BiVO4films showed a porous morphology with the grain sizes of about 270 nm. Because the hole diffusion length of BiVO4is about 100 nm, the W-Mo-doped BiVO4film in this study is an ideal candidate for the photoelectrochemical water oxidation. Iron oxyhydroxide (FeOOH) electrocatalyst was chemically deposited on the W-Mo-doped BiVO4to investigate the effect of the electrocatalyst on the semiconductor. The W-Mo-doped BiVO4/FeOOH composite electrode showed enhanced activity compared to the pristine W-Mo-doped BiVO4electrode for water oxidation reaction. The chemical deposition is a promising method for the deposition of FeOOH on semiconductor.
