Current OER electrocatalysts are hardly applicable for industrial use, which demands high current density (≥ 1000 mA cm-2) at low overpotential (≤ 300 mV) with long-term stability (≥ 100 h). Herein self-supported heterojunction catalyst, NiCo-OH@NixFeyO4 on Fe foam (FF), is in situ synthesized using...
