▎ 摘　　要

Carbon-enhanced TiO2/graphene composite photocatalyst was prepared by two-step method. First, anatase TiO2 nanocrystals with amorphous carbon layer (C-TiO2 nanocrystals) were obtained in acetone solvothermal condition. Then, graphene was coated by reduction from graphite oxide and simultaneously combined with the C-TiO2 nanocrystals in a one pot solvothemal reaction. The structure, morphology, optical and photocatalytic properties of the samples were investigated. This carbon-enhanced TiO2/graphene shows high visible light photosensitivity and favorable photocatalytic activity toward methyl orange.
