Fig. 4: Electrocatalytic performances of SACs for water splitting.
From: Electrochemical deposition as a universal route for fabricating single-atom catalysts
a, b Polarization curves of cathodically deposited SACs for HER (a) and anodically deposited SACs for OER (b). The measurements were all conducted in 1 M KOH. c, d The overpotentials at 10 mA cm−2 for HER (c) and OER (d). The commercial Pt/C and IrO2 were used as references for HER and OER, respectively. e Polarization curves of Ir1/Co0.8Fe0.2Se2@Ni foam for overall water splitting in the two-electrode cell. The commercial Pt/C-IrO2 coupled electrolyzer was used as a reference. f Chronopotentiometric curves of Ir1/Co0.8Fe0.2Se2@Ni foam for overall water splitting at 10, 100, and 500 mA cm−2 for 100 h.
