Electrocatalysis OER of FeCoNiCr hydroxide in 1 M KOH. (a) iR-corrected LSV curves of FeCoNiCr, FeNiCr, FeCoCr, FeCoNi, FeNi, FeCo catalysts in 1 M KOH. (b) Overpotentials required for j=10 mA cm−2 of different catalysts. (c) Tafel plots of different catalysts. (d) TOFs calculated at 1.58 V assuming all metal sites were involved in OER of different catalysts. (e) Potentiostatic curve of FeCoNiCr at a current density of 10 mA cm−2.
