In the present study, composites incorporating NiO-Co3O4 (NC) and CuO-NiO-Co3O4 (CNC) as active electrode materials were produced through hydrothermal method their performance was investigated systematically. The composition, formation, nanocomposite structure of fabricated material characterized by XRD, FTIR, UV–Vis. FE-SEM analysis revealed presence rod spherical mixed morphologies. prepared NC CNC samples utilized supercapacitor electrodes, demonstrating specific capacitances 262 Fg−1 at a current density 1 Ag−1. Interestingly, composite displayed notable long-term cyclic stability 84.9%, which observed even after 5000 charge–discharge cycles. exceptional electrochemical properties can be accredited to harmonious effects copper oxide addition, hollow structure, various metal oxides. This approach holds promise for development electrodes. These findings collectively indicate that hydrothermally synthesized nanocomposites exhibit potential high-performance electrodes applications.
