Abstract

Hydrogen evolution reaction (HER) through water splitting is a promising way to solve the energy short-age.Noble-metal-free HER electrocatalysts with high efficiency is very important for practical applica-tions.Herein,we prepare the Ni3S4@MoS2 electrocatalyst on carbon cloth (CC) through a two-step hy-drothermal process.The Ni3S4 nanorods are uniformly integrated with the MoS2 nanosheets,forming a hierarchical structure and heterogeneous interfaces.The fast electron transfer on the interface en-hances the kinetics of catalytic reaction.The hierarchical structure provides more exposed active sites.The Ni3S4@MoS2/CC exhibits good catalytic activity and long-term stability for HER.This work provided a practicable strategy to develop efficient electrocatalysts for HER in alkaline media.
