▎ 摘　　要

Herein, CdxZn1-xS-graphene composites were prepared via an in situ growth solvothermal process using sulfur-graphene composites as precursor for the first time. The as-prepared samples exhibit efficient photocatalytic activities, including the production of H-2 as well as the photo-oxidation of methylene blue dye under visible light irradiation.
