摘要：
A mesoporous ZnS shell is in situ grown on a CdS core through a one-pot surfactant-free hydrothermal route. Due to the mesoporous ZnS shell and the unique spatial distribution of the photoexcited charge carriers in the CdS-ZnS core-shell particles, the hydrogen evolution rate over CdS-ZnS is 169 and 56 times higher than that of ZnS and CdS under visible light, respectively. Moreover, the core-shell particles show excellent photocatalytic stability over 60 h.
