摘要：
A visible light-driven cadmium-free ZnS/rGO/CuS porous photo catalyst heterojunction was synthesized by simple hydrothermal and cation exchange methods using a zeolitic imidazolate framework (ZIF-8) as the template and Zn precursor. Due to the ZIF-8 templated high porous microstructure and/or the high carrier conductivity of the graphene (rGO), ZnS/CuS and ZnS/rGO/CuS heterojunctions exhibited a photocatalytic H-2-production activity 9 and 13 times larger than that of the counterpoint heterojunction derived from the inorganic precursors under visible light irradiation, respectively. This work will provide an insight into the design and synthesis of ternary composite photocatalyts with high porosity and efficient charge separation and transfer.
