Abstract

Photoelectrochemical (PEC) water splitting is a rational and effective way that imitates natural photosynthesis for direct conversion of solar energy into clean hydrogen fuels. Developing highly efficient photoanodes to enhance the kinetics of the rate-determining oxygen evolution reaction is generally regarded as the key to achieve artificial photosynthesis. Recently, bismuth vanadate (BiVO4) has emerged as a promising photoanode material for PEC applications. In this Review, recent progress in designing BiVO4-based photoanodes is presented and summarized, including morphological control, heteroatom/defect doping, hetero-/homo-junction fabrication and co-catalyst deposition. In addition, typical unbiased tandem devices of photoanode/photocathode and photovoltaic/photoanode systems using BiVO4 as the front-absorber photoanodes are reviewed. Finally, a future outlook is provided to highlight the issues to be addressed for commercial applications of PEC devices for solar water splitting.
