Abstract Developing cost‐effective hydrogen evolution reactions (HER) catalysts to replace Pt/C in alkaline seawater media remains a critical challenge. Therefore, the osmium‐osmium phosphide (Os‐OsP 2 ) catalyst is reported with heterogeneous junction through ultrafast (20 s) microwave quasi‐solid approach for seawater‐splitting under industrial‐grade current density. Experimental and theoretical analysis reveal that Os‐OsP₂ interface optimizes electronic structure: osmium (Os) sites accelerate water dissociation by lowering d‐band center, while OsP₂ promotes desorption via interfacial spillover, collectively reducing HER energy barrier. In addition, requires only 1.74 V reach 1 A cm −2 owns high price activity anion exchange membrane electrolyzer, surpassing commercial 23% efficiency identical conditions. Furthermore, it exhibits robust across wide pH range exceptional durability over 100 h seawater. Economic evaluation highlights its superior cost (85.6 dollar⁻¹), 90‐fold higher than Pt/C, production costs ($0.86 GGE⁻¹) undercutting U.S. DOE target. This study provides feasible guidance development of high‐performance, scalable from

By combining density functional theory (DFT) calculations and the cluster expansion (CE) model in an active-learning framework, we comprehensively studied distribution features of oxygen vacancies (OV's) as well their contributions to stability activity RuO2 catalyst acidic evolution reaction (OER). The results show that OV's prefer be located at bridge sites on RuO2(110) surface next-nearest-neighbor trans positions RuO6 octahedra pairs due interactions between two OV's, high concentrations exhibit a continuous zigzag (110) plane RuO2. vacancy can explained by charge repulsion low-valent Ru O, which is referred "heterovalent ion-oxygen exclusion principle". In addition, DFT presence cannot improve inherent OER specific since hinder deprotonation second water molecule. Nevertheless, suppressing lattice mechanism (LOM) path. summary, this work provides deeper insights into with media possible way performance using engineering.
