A novel oxygen evolution reaction (OER) electrocatalyst was prepared by a synthesis strategy consisting of the solvothermal growth Ni3S2 nanostructures on Ni foam, followed hydrothermal incorporation Fe species (Fe–Ni3S2/Ni foam). This displayed low OER overpotential 230 mV at 100 mA·cm–2, Tafel slope 43 mV·dec–1, and constant performance an industrially relevant current density (500 mA·cm–2) over h in 1.0 M KOH electrolyte, despite minor loss process. Based detailed characterization (in situ) Raman spectroscopy, (quasi-in XPS, SEM, TEM, XRD, ICP-AES, EIS, Cdl analysis, high activity stability Fe–Ni3S2/Ni foam were attributed to nanostructuring surface form stable nanosheets combination granting suitable electrical conductivity with newly formed NiFe-based (oxy)hydroxides material providing active sites for OER.

Fe has been reported to play a crucial role in improving the catalytic activity and stability of Ni/Co-based electrocatalysts for oxygen evolution reaction (OER), while effect remains intangible. Here, we design several experiments identify improvement using porous anodized nickel foam (ANF) as electrode 1.0 M KOH containing 1000 μM Fe(III) ions electrolyte. Systematic investigations reveal that Ni sites serve hosts capture create active FeNi-based intermediates on surface ANF improve OER significantly, regulate equilibrium maintain long time. The system exhibits 242 343 mV overpotentials reach 10 mA cm
