Abstract

The specific capacitances (SC) of cadmium oxide (CdO) films synthesized electrochemically followed by air annealing at 673 K for 2 h onto tin-doped indium oxide (ITO) substrates, in different electrolytes, are estimated using cyclic voltammetry (CV) and galvanostatic discharge experiments and characterized for the structural and surface morphological studies using X-ray diffraction and scanning electron microscopy techniques, respectively. The flake-like surface morphology of CdO film has showed superior SC in KOH electrolyte than that of KNO 3 , Na 2 SO 4 and NaOH, respectively. Effect of air annealing on shape and enclosed area of CV curves is also studied. Over 1000 cycles, the film electrode was considerably stable, confirming the potentiality of CdO as a capacitive material.
