Ruthenium-Infused Nickel Sulphide Propelling Hydrogen Generation via Synergistic Water Dissociation and Volmer Step Promotion

The inclusion of ruthenium (Ru) to decorate nickel sulphide (Ru@NiS/Ni foam) resulted in a highly efficient electrocatalyst for the alkaline HER by enhancing water dissociation at the interface and reducing the energy barrier of the Volmer step.
