Synthesis and Characterization of some metals (Sn, Ni, Zn and Co) doped with CdO Nanoparticles by Co-Precipitation method for super capacitor applications

Abstract

In this present investigation, a set of pure and some metals doped Cadmium oxide nanoparticles were synthesized by the way of co-precipitation method. The precursor materials used in this current work were cadmium nitrate, tin (II) chloride, nickel acetate, zinc acetate dihydrate and cobalt (II) chloride has been make uses of a precursor materials. The as-synthesized nanopowders were characterized by XRD, FTIR, UV-Vis and SEM analysis. The X-Ray Diffraction patterns revealed a polycrystalline having the characteristic peaks are well matched with the phase purity of cubic structure. Scanning Electron Microscope exhibit surface morphology, Fourier Transform Infrared spectrum has affirmed the presence of the functional groups present in the pure and metals doped cadmium oxide nanoparticles. The room temperature photoluminescence (PL) and Ultra Violet-Vis near Infra measurement studies were carried out to optical properties and band gap of the materials. The band gaps of the materials were observed to be 2.47 eV for pure CdO, 2.32 eV for metals doped CdO which were appraise from Tauc’s plot. The average particle diameter of CdO nanoparticles was measured in the nanometer range using a dynamic light scattering (DLS) particle size analyzer. The magnetic properties to express vibrating sample magnetometer studies (VSM). The uppermost electrochemical capacitance implementation is using Cyclic Voltammetry analysis, which indicates capable electrode materials for electrochemical super capacitor applications.
