The results of fitting of the impedance spectra obtained at c_Mo = 0 and 100 mM using EECs from Fig. 6: S is the residual sum of squares and indicate the quality of the fit; R_s is the solution resistance; T_dl and α_dl are parameters of CPE_dl representing the electrical double layer; R_ct is the charge-transfer resistance; the resistance R₂ and the constant phase element CPE₂ with parameters T₂ and α₂ correspond to adsorption process, R₁ and the inductance L₁ are related to liberation of hydrogen bubbles; uncertainties of the fitted parameters, obtained from Zview, are given in brackets.
