Recently, the latest achievement of Rich active-edge-site MoS2 anchored on reduction sites in metal sulfide heterostructure: Toward robust visible light photocatalytic hydrogen sulphide splitting was published on Applied Catalysis B: Environmental. In this work, the unsaturated-sulfur-edge-rich (US-rich) MoS2 was successfully introduced in MnS/In2S3 composite by a smart S-vacancies-induced strategy. As a result, he novel MnS/In2S3-MoS2 composite is the state-of-the-art non-noble-metal visible light driven photocatalysts with H2 evolution rate of 124 μmol h-1 (49.6 mmol g-1 h-1) from H2S which is 4.5 times higher than that of the pristine MnS/In2S3 heterostructure. The corresponding apparent quantum efficiency (AQE) at 400 nm is as high as 72 %. This work presents a prototype material for exploitation the role of cocatalysts and gives insights into design of advanced photocatalysts for high-efficiency hydrogen evolution applications.
