description Hydrogenation of CO<sub>2</sub> to form methanol utilizing green hydrogen is a promising route to realizing carbon neutrality. However, the development of catalyst with high activity and selectivity to methanol from the CO<sub>2</sub> hydrogenation is still a challenge due to the chemical inertness of CO<sub>2</sub> and its characteristics of multi-path conversion. Herein, a series of highly active carbon-confining molybdenum sulfide (MoS<sub>2</sub>@C) catalysts were prepared by the in-situ pyrolysis method. In comparison with the bulk MoS<sub>2</sub> and MoS<sub>2</sub>/C, the stronger interaction between MoS<sub>2</sub> and the carbon layer was clearly generated. Under the optimized reaction conditions, MoS<sub>2</sub>@C showed better catalytic performance and long-term stability. The MoS<sub>2</sub>@C catalyst could sustain around 32.4% conversion of CO<sub>2</sub> with 94.8% selectivity of MeOH for at least 150 h.
