Exploring the Effects of the Interaction of Carbon and MoS Catalyst on CO Hydrogenation to Methanol.

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