Abstract
Abstract Ruthenium (Ru) is considered as a promising catalyst for the alkaline hydrogen evolution reaction (HER), yet its weak water adsorption ability hinders the water splitting efficiency. Herein, a concept of introducing the oxygenophilic MgO x and MoO y species onto amorphous Ru metallene is demonstrated through a simple one‐pot salt‐templating method for the synergic promotion of water adsorption and splitting to greatly enhance the alkaline HER electrocatalysis. The atomically thin MgO x and MoO y species on Ru metallene (MgO x /MoO y ‐Ru) show a 15.3‐fold increase in mass activity for HER at the potential of 100 mV than that of Ru metallene and an ultralow overpotential of 8.5 mV at a current density…
