Solar energy-driven overall water splitting (OWS) is an attractive way for generating clean and renewable green hydrogen. One key challenge is the construction of OWS systems with high solar energy conversion efficiencies, in which how to manipulate photoexcited charge carriers to efficiently participate in the reaction is the top priority. In recent years, bismuth vanadate (BiVO ) has emerged as one of the most promising materials for photo(electro)catalytic OWS and considerable progress has been achieved. In this review, recent advances of BiVO -constituted OWS systems in both photoelectrocatalytic and photocatalytic approaches are presented in a mainline of effective charge carrier utilization. Various strategies for improved charge carrier utilization, including band structure engineering, improving charge separation, reducing charge recombination, and accelerating reaction kinetics, are summarized and analyzed in detail. Finally, perspective and outlook on further exploring the application potential of BiVO are proposed.
太阳能驱动的全水解（OWS）是一种极具吸引力的生产清洁可再生绿色氢气的方式。一个关键挑战是构建具有高太阳能转换效率的OWS系统，其中如何操控光激发电荷载流子以有效参与反应是首要任务。近年来，钒酸铋（BiVO₄）已成为光（电）催化OWS最有前景的材料之一，并取得了显著进展。在本综述中，以有效电荷载流子利用为主线，介绍了BiVO₄构成的OWS系统在光电催化和光催化方法方面的最新进展。详细总结和分析了提高电荷载流子利用率的各种策略，包括能带结构工程、改善电荷分离、减少电荷复合以及加速反应动力学。最后，对进一步探索BiVO₄的应用潜力提出了展望。
