Abstract

Herein, a mesh carbon-coated MoSe₂/Mo₂CT_x hybrid material (MoSe₂/Mo₂CT_x@C) is proposed as an effective catalyst for electrochemical hydrogen evolution reaction (HER). On one hand, the highly conductive Mo₂CT_x substrate enhanced charge transfer ability and effectively prevented the agglomeration of MoSe₂ nanosheets to expose abundant active sites. On the other hand, the carbon coating layer further improved the conductivity and effectively prevented Mo₂CT_x from being oxidized in the environment. Consequently, the unique MoSe₂/Mo₂CT_x@C hybrid material exhibited excellent HER performance. Specifically, the MoSe₂/Mo₂CT_x@C catalyst only required an overpotential of 108.3 mV to reach a current density of 10 mA cm⁻² and displayed excellent durability under long-term cycling in acidic solution. This research highlights the potential applications of MXene-based composite materials in the energy field.
