Abstract:

The research work involves the development of better, inexpensive, reliable, easily and accurate method for the fabrication of novel metal oxide nanoparticles-based nanocomposite materials through green synthetic method. The characterization of the nanostructured nanocomposite materials will use various techniques, including High Resolve Transmission Electron Microscope (HRTEM) technique for the physical property such as morphology, particle size, structure and particle distribution; Fourier transform infrared spectroscopy (FTIR) for the composition and purity of the product; Ultraviolet-vis spectroscopy (UV/Vis spectra) Photoluminescence (PL) analysis for optical studies; X-ray diffraction (XRD) for purity and crystalline structure; Thermal studies by DSC/TGA technique for change phases and weight loss and Electrochemical methods such as cyclic, square wave voltammetry and electrochemical impedance spectroscopy for the evaluating the electrochemical activities. The electrochemical dynamics as a sensor or electrochemical catalyst of the nanostructured crystalline multi-metallic will be studied using cyclic voltammetry and Electrochemical Impedance Spectroscopy (EIS). The development of electrodes is prepared by drop coating the metal oxide nanoparticles-based nanocomposite materials on the surface area of electrode (Glassy carbon/Platinum) electrode for electrochemical application.
