Reduced Graphene Oxide-Tailored CuFe2O4 Nanoparticles as an Electrode Material for High-Performance Supercapacitors

Transition metal oxide-based magnetic nanocomposites attract great attention due to their unique properties and applications in the field of energy storage. Herein, we present a facile microwave procedure for synthesis CuFe2O4 (CF) incorporated with reduced graphene oxide CuFe2O4/rGO (CG) as potential electrode materials hybrid supercapacitor. The structure morphology CF CG nanoparticles are examined. electrochemical performance is studied 6 M aqueous KOH electrolyte using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), impedance spectroscopy (EIS) techniques. attractive nanocomposite exhibits high specific capacity 800 C/g at current density 2 A/g better cycling stability when compared pure CF, formation nanostructure composed ferrite homogeneously onto rGO sheets. Furthermore, practicability investigated by fabrication activated carbon. supercapacitor device shows excellent 18.3 Wh/kg power 455 W/kg. It noteworthy that retention ~98% after 3000 cycles manifesting superiority electrode. proposed demonstrates fabricate other oxides carbon via method promoting application storage new opportunities binary nanocomposite.
