Ru Cluster Incorporated NiMoO(P)₄ Nanosheet Arrays as High-Efficient Bifunctional Catalyst for Wind/Solar-To-Hydrogen Generation Systems.

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 m
