Abstract

Abstract In recent times, the convergence of metal oxide adorned graphene oxide (GO) composites has ignited substantial notice, driven by their potential to revolutionize electrochemical energy storage applications, particularly in the realm of supercapacitors. This surge in attention is attributable to the harmonious amalgamation of metal oxide nanoparticles with the versatile GO sheets, resulting in intricately nanostructured materials. The present investigation the synthesis of hybrid done by hydrothermal route, yielding nanostructured Co3O4/GO. Extensive electrochemical assessment reveals a pinnacle specific capacitance of 786.69 F/g at 1 mA/cm2 current density within a 3 mol L−1 KOH aqueous medium, accompanied by commendable rate-handling capabilities.
