(a) Cyclic voltammograms of CNT, BDD and BDD–CNT electrodes in a 3 M KCl solution containing 10 mM Fe(CN)63−/4− at a scan rate of 50 mV s−1. (b) Peak currents as a function of scan rate for determining the effective surface areas of the CNT, BDD and BDD–CNT core-shell network electrodes. (c) Nyquist plots for the CNT, BDD and BDD–CNT electrodes in a 0.1 M KCl solution containing 5 mM Fe(CN)63−/4−.
