摘要：

This paper presents a novel visible-light photocatalyst, graphene-modified Ag2S (GR/Ag2S), prepared by a facile and effective hydrothermal method with AgNO3, thioacetamide and graphene oxide (GO) as the precursor. The catalytic activities of the GR/Ag2S hybrids with different GR content (2%, 4%, 6%) were evaluated by photocatalytic decolourisation of rhodamine B (RhB) solution under visible-light irradiation. The improved photocatalytic activity of GR/Ag2S composites compared with pure Ag2S is observed and attributed to the enhanced absorption of organic dyes and increased separation efficiency of photogenerated electron-hole pairs. The 4% GR/Ag2S sample exhibits the best photocatalytic activity than the others.
