Solar‐driven H2 evolution is an essential process for sustainable energy development. Currently, the greatest challenge is the development of efficient photocatalysts to drive this reaction, especially in pure water systems (without the use of a sacrificial agent). In this study, structural defects in Zn–Cd–S nanorod photocatalysts are found to increase charge separation efficiency significantly by sevenfold. Efficient H2 evolution (352.7 μmol h−1 g−1, 100 mg of catalyst) is achieved by using this defective Zn–Cd–S nanorod photocatalyst in the absence of sacrificial agents and precious metal cocatalysts under visible‐light irradiation. Thus, this cocatalyst‐ and sacrificial‐agent‐free, visible‐light‐responsive system shows remarkable potential as a new artificial photosynthesis route for green H2 production.

在不使用牺牲剂或助催化剂的情况下,用于可见光驱动氢释放的有缺陷的锌-镉-硫纳米棒的构建

太阳能驱动的H 2释放是可持续能源发展的重要过程。当前,最大的挑战是开发有效的光催化剂来驱动该反应,特别是在纯水系统中(不使用牺牲剂)。在这项研究中,发现Zn-Cd-S纳米棒光催化剂中的结构缺陷可将电荷分离效率显着提高七倍。有效释放H 2(352.7μmolh -1  g -1,100 mg的催化剂)是通过使用这种有缺陷的Zn-Cd-S纳米棒光催化剂,在可见光照射下不存在牺牲剂和贵金属助催化剂的情况下实现的。因此,这种无助催化剂和无牺牲剂的可见光响应系统显示了巨大的潜力,可作为生产绿色H 2的新的人工光合作用途径。
