Water dissociation in anion exchange membrane water electrolysis (AEMWE) faces significant energy barriers, posing a challenge for reducing cell voltage. Herein, we engineered CoP nanosheets by doping Er and hybridizing with NiCoP to optimize local electronic states accelerate H2O during the hydrogen evolution reaction. The resulting Er0.1-CoP/NiCoP catalyst achieves low overpotential of 154 mV at -500 mA cm-2 1.0 M KOH. An AEM electrolyzer comprising an Er0.1-CoP/NiCoP@NF cathode demonstrates voltage 1.672 V stability exceeding 1000 h 500 (50 °C). Characterization, density functional theory (DFT) calculations, ab initio molecular dynamics (AIMD) simulations reveal that hybridization synergistically modulate charge distribution across multisites, shifting p-band centers away from Fermi level. These adjustments free H* adsorption (ΔGH*) improve OH*/H2O* adsorption, thereby facilitating H2 evolution.
