Developing cost-effective electrocatalysts for efficient seawater splitting requires a fundamental understanding of the oxygen evolution reaction (OER) mechanism. Herein, iron-doped nickel phosphide (Fe-Ni2P) is synthesized via hydrothermal-impregnation-phosphidation strategy to investigate role Fe incorporation in modulating electronic structure and OER pathways. Mechanistic investigations demonstrate that doping triggers shift from adsorbate mechanism (AEM) lattice oxygen-mediated (LOM) pathways, evidenced by pH-dependent kinetics, tetramethylammonium cation probing, situ electrochemical impedance spectroscopy (EIS). The LOM involves nonconcerted proton-electron transfers, facilitated accelerated hydroxide adsorption (ks = 0.275 s-1) dynamic surface reconstruction into amorphous NiOOH. reduced activation energy (27.1 kJ mol-1) lower charge-transfer resistance Fe-Ni2P underscore its superior thermodynamics kinetics. X-ray photoelectron EIS further validate vacancy accumulation during process. Electrochemical studies reveal exhibits low overpotential 220 mV at 10 mA cm-2 remarkable stability through phosphate-mediated Cl- repulsion involving alkaline seawater. This work establishes Fe-induced modulation as critical activating LOM-dominated catalysis transition metal phosphides.
