Support Effect of Zinc Oxide Catalyst on Synthesis of Methanol from CO2 and H2

Abstract
The synthesis of methanol from CO2+H2 was carried out at 340–400 °C under total pressure of 10 atm over ZnO supported on MgO, Al2O3, SiO2, TiO2, ZrO2, and Nb2O5. The ZnO/ZrO2 catalyst showed high activity and selectivity for methanol formation. The hydrogenation of CO2 was more selective for methanol synthesis than that of CO.
