Synthesis and Electrochemical Performance of ZnO:MnO:VO Ternary Metal Oxide Nanocomposite for Supercapacitor Applications

Published: April 3, 2025

This investigation describes both the synthesis process and detailed inspection of ZnO:MnO:VO nanocomposites which were made through hydrothermal processing subsequent heating treatment. X-ray diffraction results showed that prepared nanocomposite structure primarily contained FCC phase MnO small amounts Wurtzite ZnO Orthorhombic VO phases. The contains tiny crystalline grains rabged from 1.50 to 3.71 nm, as determined Debye-Scherrer formula. characteristic FTIR vibrational modes metal-oxygen (M–O) bonds validated composite formation in analysis. Scanning Electron Microscope rod-shaped components with lengths 1 µm 10 Energy Dispersive Spectroscopy demonstrated all four atomic elements Zn, Mn V O existed evenly throughout structure. structural analysis strong content complete purity because no additional impurities present. electrochemical assessment took place CV GCD EIS testing 1M KOH aqueous electrolyte. specific capacitance by found 232.11 Fg⁻¹ 222.75 respectively. morphological properties are suitable for supercapacitor applications finds high capacitive devices.
