    • Abstract


      This work comprises a facile synthesis of cerium dioxide nanoparticles (CeO$_2$ NPs) using hydrothermal method. The characterization of the CeO$_2$ NPs was carried out using different techniques such as powder X-ray diffraction, Fourier transform infrared spectroscopy, high-resolution transmission electron microscopy and ultra-violet visible spectroscopy. The photocatalytic activity of the CeO$_2$ NPs was evaluated for the degradation of methylene blue under the sunlight irradiation. CeO$_2$ NPs, nanosphere obtained by the hydrothermal decomposition showed the highest photocatalytic efficiency (74.04%) due to their nanosize. Electrochemical impedance spectroscopy, galvanostatic charge/ discharge and cyclic voltammetry were used to examine the electrochemical properties of the electrode prepared using CeO$_2$ nanoparticles. The CeO$_2$ nanoparticles showed a specific capacitance of 91.75 F g$^{-1}$ at a current density of 1 A g$^{-1}$.
