Anion exchange membrane water electrolyzer (AEMWE) represents a promising sustainable method for large-scale industrial-grade hydrogen manufacturing. However, the sluggish kinetics of bifunctional oxygen/hydrogen evolution reaction (OER/HER) electrocatalysts makes it imperative to develop high-performance anode and cathode materials. Herein, P-doped β-phase NiMoO4 (p-β-NiMoO4) nanorods were first constructed as material HER, then α-phase (p-β-NiMoO4-A) derived by an electrochemical phase transformation mechanism was further applied OER. A series characterizations supported that applying sufficient potential β-NiMoO4 can drive from beta alpha. Compared with directly prepared counterpart, this dynamic results in catalyst tuning atomic configuration environment, modifying electronic state, optimizing *OH adsorption ability. Consequently, assembled two-electrode electrolytic cell system contributes remarkable overall water/seawater splitting capacity outstanding long-term durability even under operating conditions. The AEMWE device ultralow voltage 2.15 V at 2.0 A·cm–2 current density confirms applicability electrocatalysts. This study could provide path realize efficient transition nickel–molybdenum-based materials industrial clean energy conversion.
