Abstract

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.

摘要

利用绿色氢气将 CO 加氢转化为甲醇是实现碳中和的一种很有前途的途径。然而，由于 CO 的化学惰性及其多路径转化的特点，开发具有高活性和甲醇选择性的 CO 加氢催化剂仍然是一个挑战。在此，通过原位热解法制备了一系列具有高活性的碳限域的硫化钼（MoS@C）催化剂。与体相 MoS 和 MoS/C 相比，MoS 与碳层之间的相互作用明显增强。在优化的反应条件下，MoS@C 表现出更好的催化性能和长期稳定性。MoS@C 催化剂在至少 150 h 的时间内可以维持约 32.4%的 CO 转化率和 94.8%的甲醇选择性。
