Description
Summary:•BiVO4 has been regarded as one of the most promising photoanodes for photoelectrochemistry.•Bulk, interface, and surface modification of BiVO4 photoanodes are important to enhance their photoelectrochemical performance.•BiVO4 photoanodes have shown excellent performance for water splitting, chemical production, and organic degradation.•Further modification of BiVO4 to reduce its bandgap is necessary to achieve a new breakthrough. Solar water splitting is an emerging technology for producing clean and renewable hydrogen fuel from sunlight and water. Among various photoelectrode materials, bismuth vanadate (BiVO4) has attracted considerable attention due to its visible light absorption, favorable band edge positions, good chemical stability, and low cost. However, the solar water splitting efficiency of BiVO4 photoanodes is still far from satisfactory, mainly because of the low charge carrier mobility, high recombination rate, and slow water oxidation kinetics. In this review, we summarize the recent progress in the synthesis, modification, and application of BiVO4-based photoelectrodes for photoelectrochemical (PEC) water splitting. The working principle of PEC water splitting and the fundamental properties of BiVO4 are introduced. Then, the synthesis methods of BiVO4 films are reviewed, and the strategies to enhance the PEC properties of BiVO4 are critically discussed. Furthermore, the applications of BiVO4-based photoelectrodes in different scenarios are highlighted. Finally, the summary and outlook for the future development of BiVO4-based photoelectrodes for PEC water splitting are presented. [Display omitted]
