Copper oxide nanoparticles (CuO-NPs) were synthesized by a hydrothermal method with different morphologies including nanorod, spherical, rock like and plate. Their structural properties, functional groups, surface morphology, pore size distribution electrochemical properties studied techniques X-ray diffraction, vibrational spectroscopy, Scanning Electron Microscopy cyclic voltammetry. XRD analysis confirmed the formation of orthorhombic structure reduced crystallite 13.23 nm. The morphology average particle identified SEM. FTIR studies expressed presence bands in range 493 cm-1 610 ascribed to CuO bonds, respectively. XPS showed oxidation state presented elements prepared sample. Typical pseudocapacitance behavior was recorded for electrode, which shows specific capacitance value 197 Fg−1 at 10 mVs-1.The stability electrode material maximum 77.24 % retention electrode. Moreover, impedance spectral revealed excellent rate-capability reversible nature In conclusion, nanoparticle electrodes proved their viable applicability development high-performance supercapacitors.
