Highly photocatalytic activities of magnetically separable reduced graphene oxide-CoFe2O4 hybrid nanostructures in dye photodegradation

Because the photogenerated electron transformation from the CoFe2O4 to the rGO, their hybrids showed obviously greater sunlight-excited photocatalytic and Fenton-like photocatalytic activities to the dye degradation. The effects of initial pH and H2O2 concentration were studied. The strong ferromagnetic property of the nanoparticles and hybrids provides a well magnetic separation performance.153
