Efficient and stable nonprecious metal-based oxygen evolution reaction (OER) electrocatalysts are pivotal for water electrolysis technology. Herein, we reporting an effective strategy fabricating efficient Co-based OER by low-level Fe doping in CoMoO4 to boost surface reconstruction electronic modulation, which resulted excellent electroactivity consequently. Our findings reveal that a mere 5.30% (wt %) of can raise the O 2p band center energy nearer Fermi level, reduce barrier vacancy (VO) formation, significantly enhance electrocatalytic activity. Additionally, fast dissolution Mo initial facilitated form active oxyhydroxide species stabilized Co from leaching. As result, optimized catalyst Fe-CoMoO4-0.2 exhibited low overpotential 276 mV at 10 mA cm-2 1 M KOH operate stably current density 20 least 24 h under splitting conditions. This work provides example regulating structure properties catalysts.
