Abstract Developing efficient, multifunctional electrodes for energy storage and conversion devices is crucial. Herein, lattice strains are reported in the β‐phase polymorph of CoMoO 4 within @Co 3 O heterostructure via phosphorus doping (P‐CoMoO ) used as a high‐performance trifunctional electrode supercapacitors (SCs), hydrogen evolution reaction (HER), oxygen (OER) alkaline electrolytes. A tensile strain +2.42% on P‐CoMoO results superior electrochemical performance compared to . The optimized achieves high density 118 Wh kg −1 an asymmetric supercapacitor low overpotentials 189 mV HER 365 OER at current 500 mA cm −2 This overall water splitting voltage 1.71 V same making it effective bifunctional 1 m KOH freshwater electrolyte. Theoretical analysis shows that excellent can be attributed interfacial interactions between Co , which lead strong OH − adsorption barriers intermediates. Practical application demonstrated by using ‐based ASCs self‐generate (H 2 ||P‐CoMoO seawater electrolyzer, showcasing its potential future technologies.
