An efficient Ni₃S₂–Ni electrode constructed by a one-step powder metallurgy approach for the hydrogen evolution reaction

Abstract

A one-step powder metallurgy process using Ni and nano S powder was proposed to prepare a Ni3S2–Ni electrode. Numerous Ni3S2 nano protuberances on the surface and strong bonding between inter-connected Ni networks significantly improve the catalytic performance and durability of the HER.
