3D Porous Hierarchical Nickel–Molybdenum Nitrides Synthesized by RF Plasma as Highly Active and Stable Hydrogen‐Evolution‐Reaction Electrocatalysts

Nickel–molybdenum bimetallic nitride dendritic nanofilms are obtained by a fast and environmentally friendly N2-plasma-activation method. The bimetallic nitride film has a 3D porous dendritic nanostructure and demonstrates outstanding catalytic activity for the hydrogen-evolution reaction in an alkaline electrolyte.
