A Mo-cation/O-anion doping strategy for creating vacancy defects and cation multivalency to enhance the hydrogen evolution of ZnS under visible light

A stable and photocorrosion-resistant Mo-cation/O-anion co-doped ZnS with sulfur vacancy defects and bivalent Mo 4+ /Mo 6+ states exhibits an excellent photocatalytic hydrogen evolution activity of 41.6 mmol g −1 h −1 under visible light.
