Fe<sub>2</sub>O<sub>3</sub>/Reduced Graphene Oxide/Fe<sub>3</sub>O<sub>4</sub> Composite in Situ Grown on Fe Foil for High-Performance Supercapacitors
No full textA Fe<sub>2</sub>O<sub>3</sub>/reduced graphene oxide (RGO)/Fe<sub>3</sub>O<sub>4</sub> nanocomposite in situ grown on Fe foil was synthesized via
a simple one-step hydrothermal growth process, where the iron foil
served as support, reductant of graphene oxide, Fe source of Fe<sub>3</sub>O<sub>4</sub>, and also the current collector of the electrode.
When it directly acted as the electrode of a supercapacitor, as-synthesized
Fe<sub>2</sub>O<sub>3</sub>/RGO/Fe<sub>3</sub>O<sub>4</sub>@Fe exhibited
excellent electrochemical performance with a high capability of 337.5
mF/cm<sup>2</sup> at 20 mA/cm<sup>2</sup> and a superior cyclability
with 2.3% capacity loss from the 600th to the 2000th cycle
