Performance Exploration of Ni-Doped MoS₂ in CO₂ Hydrogenation to Methanol.

ABSTRACT: The preparation of methanol chemicals through CO₂ and H₂ 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 CO₂ hydrogenation to methanol. In-plane sulfur vacancies of MoS₂ can be the catalytic active sites for CH₃OH formation, but the edge vacancies are more inclined to the occurrence of methane. Therefore, MoS₂ and a series of MoS₂/Ni_x and MoS₂/Co_x catalysts doped with different amounts are prepared by a hydrothermal method. A variety of microscopic characterizations indicate that Ni and Co
