Abstract
Photoelectrochemical water splitting is one of the most promising and appealing strategies for converting sunlight into sustainable hydrogen energy and has received increasing attention. Among the potential photocatalysts, BiVO4 has attracted particular attention as a photoanode material because of its appropriate bandgap (2.4 eV) and favorable band-edge position. Moreover, its carrier mobility and hole-diffusion length are modest, and the photocurrent density is below the theoretical expectation (7.5 mA cm−2). Recently, diverse strategies have been developed to improve the performance of BiVO4-based photoanodes with rapid progress. In this article, engineering strategies including facet tailoring, intrinsic and extrinsic doping, surface modification, are summarized, and remaining challenges and perspective for the future research are provided.
期刊介绍：
ChemElectroChem is aimed to become a top-ranking electrochemistry journal for primary research papers and critical secondary information from authors across the world. The journal covers the entire scope of pure and applied electrochemistry, the latter encompassing (among others) energy applications, electrochemistry at interfaces (including surfaces), photoelectrochemistry and bioelectrochemistry.
