Abstract: This paper discusses results obtained on CuO/Co3O4 nanoparticles synthesized through simple hydrothermal method with aid of the surfactant (Disodium citrate). The morphology and structure of the samples were examined through SEM, XRD and FTIR studies. Electrochemical investigations of the CuO/Co3O4 samples were studied through CV (cyclic voltammetry), (CHDH) charge- discharge and (EIS) impedance analysis by gel electrolyte. Specific capacitance value of 959 F g-1 at a scan rate of 2 mV s-1 was obtained. From EIS analysis, a low RCT value of 1.06 Ω was attained. Based on the electrochemical performance and ease synthesis method indicate that the prepared electrode (CuO/Co3O4) is suitable candidate for supercapacitor applications.
