Hydrogenation of CO2 to ethanol is one of the promising and emerging routes for the transformation of CO2 into value-added chemicals. In the present work, series of CoMoCx catalysts were prepared by using ionic liquids as all-in-one precursors and adjusted the proportional and electronic properties of CoMoCx catalysts by modifying carburization temperature, the efficiency of CO2 to ethanol hydrogenation was optimized. Under the optimal reaction conditions (180 °C and 2 MPa), the selectivity of ethanol reached 97.4 %, and the yield of ethanol arrived at 0.528 mmolgcat.−1h−1. In situ DRIFTS results revealed that a nucleophilic attack on the carbon of CH3O* by a formyl to form ethanol.
