Abstract GrapheneBiFeO3 nanoscaled composites were prepared with a sol–gel method and evaluated as highly efficient photo-Fenton like catalyst under visible light irradiation. The grapheneBiFeO3 composite had a specific surface area of 35.07m2g−1, being considerably larger than that of BiFeO3 nanoparticles (7.50m2g−1). The composite exhibited excellent visible light-Fenton like catalysis activity, being influenced by calcination temperature, graphene content and solution pH value. Under optimal conditions with visible light irradiation, the grapheneBiFeO3 composite yielded fast degradation of tetrabromobisphenol A with a apparent rate constant of 1.19min−1, which was 5.43 and 3.68 folds of that achieved by using BiFeO3 and the mixture of BiFeO3 and graphene, respectively. The significantly enhanced visible light-Fenton like catalytic properties of the grapheneBiFeO3 composite in comparison with that of BiFeO3 was attributed to a large surface area, much increased adsorption capacity and the strong electron transfer ability of graphene in the composite.
