Synthesis of pure, Cu and Zn doped CdO nanoparticles by co-precipitation method for supercapacitor applications

Pure, Copper and Zinc doped Cadmium oxide was incorporated by the co-precipitation method. In this preparation method cadmium chloride, copper chloride, zinc chloride has been utilized as a precursor material. X-Ray Diffraction pattern, Fourier Transform Infrared spectrum and, Energy-Dispersive X-Ray Spectrum have affirmed the presence of the copper and zinc doped cadmium oxide nanoparticles. Scanning Electron Microscope uncovered the surface morphology, Ultra Violet-Vis Near Infra analysis and the optical band gap of the materials were observed to be 2.48 eV for Pure CdO, 2.35 eV for Cu-CdO and 2.28 eV for Zn-CdO which were assessed from Tauc's plot. The predominant electrochemical capacitive execution using Cyclic Voltammetry which indicates that the material has the ability to form a capable electrode material for stable and high-performance electrochemical supercapacitors.
