摘要: 光电化学(PEC)水分解是将太阳能转化成氢能的关键技术之一。在众多半导体光阳极材料中,BiVO4因其适中的带隙(2.4-2.5 eV)、良好的化学稳定性、环境友好以及易于合成等优点,被视为是一种极具潜力的候选材料。然而,其PEC效率受到载流子迁移速率以及严重的体相与表面复合的限制。近期研究表明,通过针对性的改性策略可以有效克服这些瓶颈,显著提升BiVO4的光电化学性能。本文系统综述了关键的优化策略,包括纳米结构调控、掺杂(本征/外源)、异质结构筑、表面钝化以及助催化剂负载,并分析了这些策略对电荷分离与传输动力学的影响。最后,对BiVO4基光电化学系统未来的研究方向进行了展望。

Abstract: Photoelectrochemical (PEC) water splitting represents a pivotal technology for solar-to-hydrogen energy conversion. Among semiconductor photoanode materials, BiVO4 has emerged as a highly promising candidate owing to its optimal bandgap (2.4-2.5 eV), exceptional chemical stability, environmental inertness, and facile synthesis. Nevertheless, its PEC efficiency is constrained by sluggish charge carrier transport kinetics and substantial bulk/surface recombination. Recent studies have demonstrated that these limitations can be effectively mitigated through targeted modification strategies, leading to significant enhancements in the photoelectrochemical performance of the BiVO4. This review systematically examines key optimization approaches, including nanostructure engineering, doping (intrinsic/extrinsic), heterojunction construction, surface passivation, and cocatalyst loading, while evaluating their impacts on charge separation and transport dynamics. Finally, we present perspectives on future research directions to advance BiVO4-based PEC systems.
