Abstract This work involved the hydrothermal synthesis of rGO/Co3O4@Ni nanocomposites at low temperatures, followed by annealing 600°C. The microstructural and electrochemical characteristics nanostructured were evaluated in detail. A Co3O4 cubic structure with space group Fd̅3m(227) distinct peaks (220), (311), (222), (400), (422), (511), (440) planes was formed, according to XRD analysis. Raman measurements confirmed presence Co-O bonds provided detailed information on microstructure samples. SEM analysis shape surface architecture demonstrated unique properties porous nanoparticles. existence Co2+ Co3+ ions verified XPS. improved stability a peak capacitance 1056 F/g current density 1 A/g tests carried out an aqueous 1M KOH electrolyte.
