▎ 摘  要

NOVELTY - Preparation of polymetallic sulfide/graphene composite visible-light-driven photocatalyst involves dispersing two or more metal diethyldithiocarbamate as sulfide precursor in surfactant-containing solution, mixing obtained solution with graphene oxide dispersion and carrying out thermal decomposition reaction to obtain polymetallic sulfide/graphene composite nanomaterials. USE - The method is useful for preparing polymetallic sulfide/graphene composite visible-light-driven photocatalyst, which is useful for visible light photocatalytic hydrogen production from water and degrading pollutants in water (claimed). ADVANTAGE - The method ensures simple and economical preparation of polymetallic sulfide/graphene composite visible-light-driven photocatalyst with high yield, catalytic efficiency and cycle stability.
