Constructing three-dimensional porous Ni/Ni3S2 nano-interfaces for hydrogen evolution electrocatalysis under alkaline conditions

A facile, two-step synthetic approach was developed to produce a novel, three-dimensional porous Ni/Ni₃S₂ nanostructured catalyst. This unique structure can expose sufficient Ni/Ni₃S₂ interfaces to the electrolyte to obtain synergetic catalytic effects.
