Figure 3. Cyclic voltammograms were taken during the aging of films in various purities of KOH. A total of 13 CV scans are shown for each sample: one for the initial as-deposited film (the dark purple), and one additional scan after each 5 min aging period up to a total of 1 hour of aging (the dark red). The changes in the anodic and cathodic peak positions (ΔEp,a and ΔEp,c) are labeled for each set of CVs. (ΔEp,a value is shown for the Ni0.75Fe0.25(OH)2, as the oxidation peak is partially obscured by the OER current.)[
