Figure 3
Applied potential and current response from the XAS-SEC cell of a 15 mM solution of K3[Fe(ox)3] in aqueous KCl (0.2 M) subject to a 41:40 pulse flow; (a, b) immediately following the application of an oxidizing potential to a reduced sample; (c, d) during the collection of the XAS spectra. Trace (e) shows the current response for a sample where gas bubbles had formed in the WE compartment. |
