摘要	ZnO-ZnS-CdS heterostructure photocatalysts for water splitting were designed and prepared by a wet chemistry method. It was found that ZnO-ZnS-CdS heterostructures are highly active photocatalysts for H(2) evolution under simulated solar light irradiation in an aqueous solution containing SO(3)(2-) and S(2-) ions as sacrificial reagents. H(2) evolution with (ZnO)(2)-(ZnS)(1)-(CdS)(1) heterostructure reaches up to 2790 mu mol h(-1) g(-1). The photoexcited electrons in the ZnO-ZnS-CdS heterostructures have a much longer lifetime (>225 ns) than that of the sole ZnO, ZnS, and CdS (<65 ns). The favorable interface processes of the heterostructures make a significant contribution to high photocatalytic H(2) evolution rate.
