Fig. 3. (A) CVs of ITO|mesoITO|CoP³ in DMF/TBABF₄ electrolyte (0.1 M) at different scan rates (10, 20, 50, 100 mV s^–1). Inset: The correlation between the peak current density, Jp (Co^II/Co^I), and scan rate, v, is shown. The black and red traces represent linear fits to the data points. (B) Consecutive CVs of ITO|mesoITO|CoP³ in DMF/TBABF₄ (0.1 M) at a scan rate of 100 mV s^–1 showing cathodically induced replacement of the axial bromido ligand by DMF. The background of ITO|mesoITO without catalyst is shown as dotted line. Note that ligand exchange has already occurred in the CVs shown in (A).
