Abstract Developing cost‐efficient bifunctional water splitting catalysts is crucial for sustainable hydrogen energy applications. Herein, ruthenium (Ru)‐incorporated and phosphorus (P)‐doped nickel molybdate (Ru‐NiMoO(P)4) nanosheet array catalysts are synthesized. Due to the synergy of Ru clusters and NiMoO(P)4 by the modulated electronic structure and the rich active sites, impressively, Ru‐NiMoO(P)4 exhibits superior OER (194 mV @ 50 mA cm−2) and HER (24 mV @ 10 mA cm−2) activity in alkaline media, far exceeding that of commercial Pt/C and RuO2 catalysts. Meanwhile, as bifunctional catalyst, to drive the overall water splitting at the current density of 10 mA cm−2, Ru‐NiMoO(P)4 requires only 1.45 V and maintaining stable output for 100 h. Furthermore, Ru‐NiMoO(P)4 also possesses excellent capability for seawater electrolysis hydrogen production. Moreover, the successful demonstration of wind and solar hydrogen production systems provide the feasibility of the ultra‐low Ru loading catalyst for large‐scale hydrogen production in the future. |
