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.
光电化学水分解是将太阳光转化为可持续氢能的最具前景和吸引力的策略之一，受到越来越多的关注。在潜在的光催化剂中，BiVO4作为光阳极材料因其合适的带隙（2.4 eV）和有利的带边位置而备受关注。此外，其载流子迁移率和空穴扩散长度适中，光电流密度低于理论期望（7.5 mA cm−2）。近年来，人们开发了多种策略来提高bivo4基光阳极的性能，并取得了快速进展。本文总结了包括面裁剪、内禀和外禀掺杂、表面改性在内的工程策略，并提出了未来研究的挑战和展望。
