Performance Exploration of Ni-Doped MoS in CO Hydrogenation to Methanol.

The preparation of methanol chemicals through CO and H gas is a positive measure to achieve carbon neutrality. However, developing catalysts with high selectivity remains a challenge due to the irreversible side reaction of reverse water gas shift (RWGS), and the low-temperature characteristics of CO hydrogenation to methanol. In-plane sulfur vacancies of MoS can be the catalytic active sites for CHOH formation, but the edge vacancies are more inclined to the occurrence of methane.
