This work deals with the study of effect of scan rate on the cyclic voltammetric performance of cupric oxide (CuO) electrodes prepared using automatic spray pyrolysis. For the synthesis via aqueous route, 50 mL of 1 m Cu(NO3)(2)center dot 3H(2)O was used as a precursor solution and stainless steel (SS) plates were used as a conducting substrates. The spray rate was maintained at 2.5 mL min(-1), decomposition temperature was kept at 673.15 K. In the analysis, XRD patterns clearly substantiate the formation of CuO on SS. Cyclic voltammetric analysis of the prepared electrodes has been carried out in 1 m KOH at various scan rates from 2 to 100 mV s(-1). In CV study, electrode shows decrease in specific capacitance (SC) values with increase in scan rates indicating reversible nature. The achieved highest value of the SC is 58.2 F g(-1).
