Abstract: Since the photocatalysis technology could transform the renewable and clean solar energy into green hydrogen (H2) energy via solar water splitting, it is regarded as the 'Holy Grail' in chemistry field in the 21st century. Unfortunately, the bottleneck of this technique still lies in the exploration of highly-active, cost-effective and robust photocatalysts. Herein, we report the design and synthesis of a novel zeolitc imidazole framework (ZIF) coupled Zn0.8Cd0.2S hetero-structured photocatalyst for high performance visible-light-induced H2 production. State-of-art characterizations and theoretical computations disclose that the interfacial electronic interaction between ZIF and Zn0.8Cd0.2S, the high distribution of Zn0.8Cd0.2S on ZIF and the atomically-dispersed coordinately-unsaturated Co sites in ZIF synergistically arouse the significantly-raised visible-light photocatalytic H2-production performance.
