摘要：
The composite catalysts were prepared by two-step photothermal synthesis, and the morphology, structure and catalytic performance of the Ag/graphene/TiO2 composite were characterized by SEM, FT-IR, XRD, etc. The results showed that the composites were prepared successfully by Ag depositing on TiO2 compounded with graphene, and solid UV diffuse reflection test showed that Ag/Graphene/TiO2 composites had the greatest enhancement in the absorption of visible light. The results showed that among four kinds materials, the methyl orange's degradation rate of Ag/Graphene/TiO2 in simulated visible light reached best, whose degradion was 4.25 times that of pure TiO2. The number of photocatalytic experiments showed that Ag/Graphene/TiO2 photogenerated electrons and the corresponding generated O-2 center dot dominated the catalysis.
