(a) Cyclic voltammograms of (A) GCE/bare and (B) GCE/MIL-53(Fe) electrodes; (b) EIS spectra (Nyquist plots) of (A) GCE/bare and (B) GCE/MIL-53(Fe) electrodes (inset: Randles equivalent circuit). Experimental conditions: K3Fe(CN)6/K4Fe(CN)6 (0.005 M) and 0.1 M KCl solution. CVs were recorded at a scan rate of 30 mV s−1. EIS spectra were measured with frequency range 100 kHz to 100 mHz, , mV.
