| Abstract |
Developing a photocatalysis system to generate hydrogen from water is a topic of great interest for fundamental and practical importance. BiVO4 Photocatalyst has suffered by the slow charge separation kinetics at solid/electrode interface that limits the photoelectrochemical performance (PEC). In order to minimize the poor properties, we modified the BiVO4 IO photocatalyst surface with an effective oxygen evolution co-catalyst using the simple synthesis route. The resulting co-catalyst coupled BiVO4 IO photoelectrode significantly improved photocurrent density and excellent photo-stability for photo-oxidation of water, which was examined under AM 1.5 G illuminations (100mW/cm2). In particular, the advantages and drawbacks of catalyst deposition routes and the role of photoelectrochemical and advanced spectroscopic techniques for elucidation of the mechanism of the photo catalytic action will be discussed in detail.
