Facile synthesis of ZnIn2S4@ZnS composites for efficient photocatalytic hydrogen precipitation

A ZnIn 2 S 4 @ZnS catalyst synthesized through a two-step process exhibits better photocatalytic H 2 production performance (2.873 mmol g −1 h −1 ) than ZnIn 2 S 4 (0.229 mmol g −1 h −1 ) under visible light due to the efficient interfacial electron transfer.
