Catalytic conversion of CO2 to methanol via hydrogenation has attracted enormous interest for its central role in CO2 utilization1 as methanol can be used not only as the starting feedstock for many other useful chemicals, but also as an alternative source in the production of liquid fuels.Currently, methanol is industrially synthesized from syngas (CO/H2) at 493-573K and 5-10 MPa using a Cu/ZnO/Al2O3 catalyst with CO2 as a co-feeder.Supported Pd catalysts (e.g.: Pd/Ga2O3, Pd/CeO2, Pd/ZnO, Pd/ZrO2) also show a good activity for methanol synthesis from CO2 hydrogenation.
