Abstract Hydrogen production by electrochemical water splitting is considered to be a key strategic energy technology, and proton exchange membrane electrolyzers (PEMWEs) anion (AEMWEs) are ideal technologies for green hydrogen in recent years. However, PEMWEs AEMWEs lack low‐cost high‐performance acidic oxygen evolution reaction (OER) alkaline (HER) electrocatalysts respectively, limiting their large‐scale development. Recently, ruthenium (Ru)‐based have received lot of attention because activity better than that commercial catalysts price more affordable, showing great potential OER HER. there still obstacles Ru‐based practical applications industrial electrolyzers, regulatory strategies need developed further optimize its performance. Herein, comprehensive review presented concerning it. First, fundamental principles focus the basic content application discussed. Then, summarized, providing detailed analysis elucidate mechanisms, properties, electrolyzers. Finally, outlooks prospects challenges future proposed.

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
