Sulfur vacancies-induced “Electron Bridge” in Ni4Mo/Sv-ZnxCd1-xS regulates electron transfer for efficient H2-releasing photocatalysis

Ni4Mo alloys were in-situ grown on the unsaturated sulfur atoms of Sv-ZCS via interfacial Ni-S bonds. Dual IEF induced by Schottky junction and sulfur vacancies promote the separation and utilization efficiency of photoinduced carriers.
