Abstract Electrochemical water splitting is a promising approach for sustainable hydrogen production, but the oxygen evolution reaction (OER) remains bottleneck due to sluggish kinetics, poor activity, and limited stability scalability. Here, Mo 2 N‐functionalized nickel designed foam (NF@Mo N) subsequently transform into N/NiSe/Ni P multi‐phase heterostructure through selenization phosphorization, address these challenges. The optimized NF@Mo catalyst integrates three key strategies: (I) functionalizing NF with N enhance conductivity charge transfer, (II) engineering collaborative multi‐interface optimize active sites (III) precisely controlling phase formation phosphorization mitigate surface reconstruction ensure long‐term stability. not only achieves an overpotential of 242 mV@10 mA cm −2 remarkable over 350 h, also low 395 mV at high current density 800 , outperforming pristine other control samples. Theoretical analysis reveals that N‐stabilized NiSe/Ni on enhances optimizes adsorption energies OER intermediates, leading improved catalytic performance This work provides new strategy designing high‐performance, non‐precious metal catalysts industrial applications advancing production.

Developing electrocatalysts with excellent activity, high stability, and low cost is vital for large-scale hydrogen production through electrochemical water splitting. Herein, a bifunctional Ni-Fe-P catalyst in situ grown on Fe foam (Ni-Fe-P/FF) developed by simple one-step solvothermal process the deep eutectic solvent (DES) of ethylene glycol choline chloride (named Ethaline). The unique environment Ethaline assisted regulating effect introduced Fe(III) ions shows an essential role governing preparation process. Ni-Fe-P/FF acts as efficient electrocatalyst splitting 1.0 M KOH, requiring overpotentials 82 mV (229 mV) 263 (370 to deliver 10 mA cm-2 (100 cm-2) oxygen evolution reactions, respectively. Furthermore, self-supported catalyst-assembled electrolyzer also exhibits good catalytic performance voltage 1.83 V drive 100 stability over h. This work offers facile approach fabricating high-performance catalyze
