A FACILE SYNTHESIS OF REDUCED GRAPHENE OXIDE/A-FE2O3 HYBRID FILMS AS SUPERCAPACITOR ELECTRODES

摘要

Due to the huge specific surface and excellent electrical conductivity, graphene has been widely used as a substrate of electrode materials for supercapacitor. The electrochemical performance of electrodes could be improved by combine carbon materials with transition metal oxides, such as NiO, CO3O4, MnO2, and Fe2O3.
