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

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) ) nanosheet array catalysts are synthesized. Due to the synergy of Ru clusters and NiMoO(P) by the modulated electronic structure and the rich active sites, impressively, Ru-NiMoO(P) exhibits superior OER (194 mV @ 50 mA cm ) and HER (24 mV @ 10 mA cm ) activity in alkaline media, far exceeding that of commercial Pt/C and RuO catalysts.

Effect of B-Doping and Manifestation on TiO-Supported IrO for Oxygen Evolution Reaction in Water Electrolysis.

To commercialize hydrogen production by proton exchange membrane (PEM) electrolysis, the amount of rare and precious metal (iridium) required for anodic oxygen evolution reaction (OER) must be greatly reduced. In order to solve the problem, carrier loading is used to reduce the amount of iridium. Unlike the carrier modified by conventional metal element doping, this work doped the carrier with the nonmetallic element and then prepared IrO/TiBO composite catalyst using the Adams melting method.
