Fe2O3 /CeO2 nanocomposite was synthesized by a chemical precipitation method in room temperature. The prepared nanocomposite has been subjected to some characterization techniques such as XRD, SEM, FTIR, CV, etc., The presence of crystalline phases of CeO2 and Fe2O3 were confirmed by the powder X–Ray diffraction analysis. Surface morphology of the prepared nanocomposite has been analyzed using SEM analysis. The functional group vibrations were analyzed by FTIR technique. The maximum specific capacitance achieved by using 1M KOH electrolyte solution is about 242 Fg-1 at 5 Ag-1 current density.
