Time-resolved Fe K-edge XANES evolution during the reductive process of a 20 mM FeIIICl3·6H2O aqueous solution in 0.1 M KCl under Ar (top left) and its re-oxidation process (top right) along a 20 mV s−1 CV. Evolution of the proportion of Fe(II) (red dots) and Fe(III) (black dots) determined by XAS during the full cyclic voltammogram (blue line) between −1 V and 0.9 V (bottom left). EXAFS spectra of a 20 mM FeIIICl3·6H2O (black dashed line) and FeCl2 (red dashed line) aqueous solution in 0.1 M KCl together with spectra collected during a cyclic voltammogram at 100 s (green line) and 190 s (blue line) after the beginning of the CV (bottom right).
