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.
