Fig. 5. (a) Cyclic voltammetry curves of BFBDTE(o) and BFBDTE(c) measured in 0.5 M Na2SO4 aqueous solution. Transient current density–time curves of BFBDTE(o) (b) and BFBDTE(c) (c) without bias potentials. (d) Electrochemical impedance spectroscopy (EIS) Nyquist plots of BFBDTE(o) and BFBDTE(c) measured at 0 V bias potentials.
