Synergistic Interaction of Clusters of Iron Oxide Nanoparticles and Reduced Graphene Oxide for High Supercapacitor Performance.

ABSTRACT: Supercapacitors have been recognized as one of the more promising energy storage devices, with great potential use in portable electronics and hybrid vehicles. In this study, a composite made of clusters of iron oxide (Fe₃O₄-γFe₂O₃) nanoparticles and reduced graphene oxide (rGO) has been developed through a simple one-step solvothermal synthesis method for a high-performance supercapacitor electrode. Electrochemical assessment via cyclic voltammetry, galvanostatic charge-discharge experiments, and electrochemical impedance spectroscopy (EIS) revealed that the Fe₃O₄-γFe₂O₃/rGO nanocomposite showed much higher specific capacitance than either rGO or bare clusters of Fe₃O₄-γFe_2</
