Enhanced photocatalytic degradation of methylene blue under visible irradiation on graphene@TiO2 dyade structure

Electron–hole recombination limits the efficiency of TiO2. We have investigated the efficacy with which the graphene@TiO2 “dyade”-like structure reduced charge recombination and enhanced reactivity. A visible-light photocatalysis of graphene@TiO2 “dyade”-like structure was synthesized, and photocatalytic degradation of organic compounds over the UV and visible-light spectrum regions was investigated. The graphene@TiO2 had anatase phase and was...
