Abstract Although ruthenium dioxide (RuO 2 ) is an efficacious oxygen evolution reaction (OER) catalyst in acidic media, its performance alkaline conditions subpar and it also ineffective for hydrogen (HER) common electrolytes. Here, effective phosphorus (P)‐doping strategy introduced to manipulate the d ‐band center of (Ru) sites, attenuating adsorption energy HER intermediates lowering barrier OER, thereby significantly accelerating both OER performance. The representative 10%P‐RuO nanofibers (NFs) presents ultralow overpotential 177.9 mV at 1 A cm −2 long‐term stability 300 h m KOH toward HER, greatly exceeding those benchmark platinum (Pt)/C catalyst. Moreover, NFs exhibits exceptional with a low 250 10 mA (η desirable 150 , which far better than commercial RuO many other typical previously reported catalysts. Additionally, overall water electrolytic cell using as anode cathode necessitates working voltage 1.52 V demonstrates over 100 outperforming electrolysis cells.

Electrolysis of seawater for hydrogen (H2) production to harvest clean energy is an appealing approach. In this context, there urgent need catalysts with high activity and durability. RuO2 electrocatalysts have shown efficient in the oxygen evolution reactions (HER OER), but they still suffer from poor stability. Herein, surface S-doped nanostructured (S-RuO2) rationally fabricated overall splitting. Doping S enhances (overpotentials 25 mV HER 243 long-term durability (1000 h at 100 mA cm–2), achieves nearly 100% Faraday efficiency (FE). Moreover, S-RuO2-based anion exchange membrane electrolyzer requires 2.01 V reach 1.0 A cm–2 under demanding industrial conditions. Experimental analysis theoretical calculations indicate that introduction could lower valence state Ru, thereby conferring enhanced Furthermore, S-RuO2 electrocatalyst highly protected by surface, which repels Cl– alkaline seawater. This investigation presents a feasible strategy designing RuO2-based splitting both performance good resistance anodic corrosion.
