CV data obtained at 3D-CB/PLA (black line) and 3D-CB/PLA–PT (red line) electrodes for (A) 2 mM [Fe(CN)6]3–/4– in 0.1 M KCl, (B) 1 mM DOP in 0.1 M HClO4, and (C) 2 mM [Ru(NH3)6]2+/3+ in 0.1 M KCl. The dashed lines correspond to the respective blank signals. CV conditions: scan rate = 50 mV s–1; step potential = 5 mV.
