Exploring the Effects of the Interaction of Carbon and MoS(2) Catalyst on CO(2) Hydrogenation to Methanol

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