Figure 13

The photocurrent transient response of the samples in a 0.2 M Na2SO4 aqueous solution without bias versus Ag/AgCl electrode under visible light irradiation (a). EIS Nyquist plots of CdIn2S4 photocatalysts synthesized at different time in 0.1 M KCl solution containing 0.1 M K3[Fe(CN)6]/K4[Fe(CN)6] (b). (Inset: Electrical equivalent circuit used for fitting of impedance spectra, RS, CSC, Rb and W represent electrolyte resistance, space charge capacitance, bulk electrode resistance and Warburg impedance, respectively.) Mott-Schottky plots for the CdIn2S4 electrodes (c). The cyclic voltammogram of BA (d), BAD (e), and NB (f) with different concentrations (0.1, 0.2 and 0.5 mmol/L).
