(a) Representative cyclic voltammograms of the CuO NR electrode anodized for 15, 20, 25, and 30 min in 0.25 M NaOH over a potential range from -1.5 to 0.5 V at a scan rate of 50 mV/s. (b) Box plots of the peak current distribution from the CV results of the CuO NR electrodes anodized for 15, 20, 25, and 30 min.
