Figure 6. CVs of (A) O-Ni/200-3 and (B) O-Ni-Fe/200-3 at different scan rates (20, 40, 60, 80, 100, and 120 mV s-1) in 1.0 M KOH at 1.024-1.624 V vs. RHE. (C) Oxidation peak current intensity versus scan rate plots. (D) TOF values as a function of overpotential. RHE: Reversible hydrogen electrode; TOF: turnover frequency values.
