Composite electrodes were fabricated for supercapacitor applications by account of studies were carried out on the synthesis and catalytic properties of pure cerium oxide based nanocomposites. In this study, CeO2-TiO2 nanocomposites has been prepared from cerium nitrate, Titanium nitrate and cetyltriethylammonium bromide (CTAB) as a precursor via hydrothermal method characterization of nanocomposites was carried out using X-ray powder Diffraction (XRD), Ultraviolet-Visible-Near Infrared (UV-vis-NIR), Fourier transform infrared spectroscopy (FTIR), High resolution Transmission Electron Microscopy (HRTEM), Room Temperature Photoluminescence (RTPL) studies and micro-Raman (µ-Raman) images indicated that the chemical molecular vibrational band structure and morphology of the product which is spherical shaped nanoparticles with an average particle size of 10 nm with standard deviation. The chemical composition of the samples and the valence states of elements were determined by X-ray photoelectron spectroscopy (XPS). The confocal microscopic studies were performed on an Olympus — confocal microscope. The mechanism of heterogeneous photocatalysis in the presence of TiO2 is also discussed.
