Abstract: The increasing demand of high-power sustainable energy storage devices based on ZnO are imperative. In this project a series of La3+ substitution in NiMoZnO have been fabricated using the solid-state technique, sintered at 1050 °C for 2 h. The structural, surface morphology, phonon-phonon interaction, functional groups, oxidation states, dielectric and electrochemical properties have been investigated in detail using X-ray diffractometer (XRD), Scanning Electron Microscope (SEM), Raman, Fourier transform infrared spectrometer, X-ray photon spectroscopy (XPS) and electrochemical workstation respectively. The structural analysis reveals the formation of hexagonal wurtzite structure without any impurity phase. The Raman Spectroscopy indicates the presence of M − O vibrational phonons modes. The FTIR evaluates the existence of functional groups of all constituent elements. XPS confirms the presence of elemental oxidation states. The electrochemical properties of sample x = 0.05 exhibit excellent specific capacitance, energy density and power density 1130 Fg-1 at 10 mVs−1 scan rate, 167 Whkg−1 and 1980 Wkg-1 respectively. On the basis of synergetic outcomes of prepared samples, they are suggested as a potential candidate for energy storage devices. [ABSTRACT FROM AUTHOR]
