In this study, a Ni3S4@MoS2 electrocatalyst on carbon cloth was successfully prepared, featuring a hierarchical structure and heterogeneous interfaces that provide more exposed active sites. The catalyst exhibited good catalytic activity and long-term stability for hydrogen evolution reaction in alkaline media.
Hydrogen evolution reaction (HER) through water splitting is a promising way to solve the energy shortage. Noble-metal-free HER electrocatalysts with high efficiency is very important for practical applications. Herein, we prepare the Ni3S4@MoS2 electrocatalyst on carbon cloth (CC) through a two-step hydrothermal 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 enhances 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.
