Abstract

Hybrid electrodes containing cobalt oxides (Co₃O₄)/ruthenium dioxide (RuO₂) decorated on graphene oxide surface materials for electrochemical supercapacitor applications. The 3D porous and nanocrystalline structured Co₃O₄@RuO₂/NGO composite was prepared by hydrothermal reaction process. The structural and morphological behaviors of the composite were examined by analytical characterization and electrode material studied via three-electrode configuration of cyclic voltammetry. The Co₃O₄@RuO₂/NGO composite electrode accomplished of ~472 F g⁻¹ (0.5 A/g) and showed increasing stability capable of 5000 cycles with 97.1% retention.
