DENG Dehui from CAS Dalian Institute of Chemical Physics and WANG Ye from Xiamen University have achieved hydrogenation of CO₂ to methanol at low temperature and with high efficiency. In situ characterizations combined with theoretical calculations demonstrated that in-plane sulfur vacancies on MoS₂ were the active centers for catalyzing a highly selective hydrogenation of CO₂ to methanol and helped to suppress undesired reverse water-gas shift (RWGS) and excessive hydrogenation of methanol to CH₄. At 180 ℃, methanol selectivity reached 94.3% at a CO₂ conversion of 12.5%. Activity and selectivity were steadily maintained for over 3000 hours.
