The synthesis and electrochemical analysis of (Ce/Mo/V) mixed metal oxide nanocomposites are widely used for supercapacitor application. In this context, the nanocomposites were synthesized from their precursors and characterized using Ultraviolet visible spectroscopy, Fourier Transform Infrared spectroscopy (FTIR), Field emission scanning electron microscope (FESEM) and X-Ray diffraction analysis. The maximum absorption (Λmax)values were used to calculate the band gap energies of the composites. IR spectrum confirms the presence of all three metal-oxide stretching vibrationswith V–O stretching vibration at 616cm−1 and Ce–O stretching is seen at 469cm−1 . XRD shows the sharp peaks which may be due to crystalline nature of the composites and the size is ~44.66 nm. The FE-SEM images show the surface morphology as agglomerated grains and the particle size is in the nanometre range. Electrochemical impedance spectroscopy (EIS) measured double layer capacitance of 1.265x10-6with the mixed metal oxide nanocomposites. The specific capacitance value is calculated to be 102 F/g for (Ce/Mo/V) mixed metal oxide nanocomposites and therefore can be a suitable electrode material for the fabrication of supercapacitor device.
