在可再生能源转换的许多策略中，光驱动的水分解产生清洁的H2代表了一种有前途的方法，近年来引起了越来越多的关注。由于水裂解的多电子/多质子转移性质，需要低成本和胜任的催化剂。沿着近二十年来金属-有机骨架材料（MOFs）的快速发展，MOFs已被公认为是一组有趣的光催化分解水的催化剂或催化剂载体。MOFs的模块化合成、固有的高表面积、可调孔隙率以及不同的金属节点和有机支柱使其成为光催化水裂解的优异催化剂候选者。迄今为止，MOFs及其衍生物作为光催化剂用于水裂解已经成为一个新兴的领域。在这里，我们展示了几个代表性的MOF为基础的光催化系统的H2和O2的演变反应（HER，OER）。具体讨论了各催化体系的设计原则。最后讨论了利用MOFs进行光催化分解水的挑战和机遇。
Amongst many strategies for renewable energy conversion, light-driven water splitting to produce clean H2 represents a promising approach and has attracted increasing attention in recent years. Owing to the multi-electron/multi-proton transfer nature of water splitting, low-cost and competent catalysts are needed. Along the rapid development of metal–organic frameworks (MOFs) during the last two decades or so, MOFs have been recognized as an interesting group of catalysts or catalyst supports for photocatalytic water splitting. The modular synthesis, intrinsically high surface area, tunable porosity, and diverse metal nodes and organic struts of MOFs render them excellent catalyst candidates for photocatalytic water splitting. To date, the application of MOFs and their derivatives as photocatalysts for water splitting has become a burgeoning field. Herein, we showcase several representative MOF-based photocatalytic systems for both H2 and O2 evolution reactions (HER, OER). The design principle of each catalytic system is specifically discussed. The current challenges and opportunities of utilizing MOFs for photocatalytic water splitting are discussed in the end.
