Abstract

A novel ZnS-WS₂/CdS composite photocatalyst for H₂ evolution under visible light irradiation has been successfully synthesized. The loading amounts of WS₂ and ZnS on the CdS surface were optimized. A H₂ evolution rate up to 1224 μmol·h^{- 1} has been achieved for the 9.6 mol% ZnS-1 mol% WS₂/CdS photocatalyst. The enhancement of the photocatalytic activity is attributed to the synergistic effect of WS₂ as co-catalyst and ZnS as passivation layer.
