Electrochemical performance of crumpled graphene loaded with magnetite and hematite nanoparticles for supercapacitors

Iron oxides have emerged as alternative electrode materials for supercapacitors because they have advantages of low cost, natural abundance, and environmental friendliness. Graphene loaded with hematite (Fe2O3) or magnetite (Fe3O4) exhibited enhanced specific capacitance as well as a high energy density. In this study, we present three-dimensional (3D) crumpled graphene (CGR) decorated with Fe2O3 and Fe3O4 nanoparticles to determine which one...
