Abstract Alloying atomically dispersed noble metals with earth‐abundant transition metal nanoparticles (NPs) presents a promising approach to enhance the hydrogen evolution reaction (HER) and oxygen (OER) in water electrolysis. However, challenge remains of reducing size NPs without sacrificing high activity durability. In this study, Ru–Co 2 Ni nanoalloy particles (NAPs) encapsulated nitrogen‐doped carbon nanotubes (NCNTs) are introduced, forming core‐shell electrocatalyst (Ru–Co Ni@NCNT). This design leverages Ru site optimization, CNT density control, strain engineering, efficient dissociation, outstanding bubble release dynamics within structure. These factors significantly improve catalytic performance low overpotentials 35 57 mV overpotential 1.0 m KOH 0.5 H SO 4 solutions, respectively, at current 10 mA cm −2 . Density functional theory (DFT) calculations reveal that while sites serve as active sites, they also modify electronic structure Co Ni, optimizing their adsorption energies improving HER efficiency. The Ni@NCNT catalyst is successfully integrated into both anion exchange membrane (AEM) proton (PEM) electrolyzers, demonstrating stable operation A for 500 h, underscoring its potential durable production.
