Electrochemical performances in 0.5 M NaOH electrolyte. (a) CV curves for MWCNTs, CeO2 and CeO2/MWCNTs electrodes at scan rate of 100 mV/s, inset shows specific capacitance of corresponding electrodes, (b) CV curves of CeO2/MWCNTs electrode at different scan rates ranging from 2 to 100 mV/s, (c) specific capacitance as a function of scan rate, (d) cycling stability at 10000 cycles, inset shows the CV curves for different cycle numbers at 100 mV/s scan rate.
