The effect of adding CO to the raw gases for methanol synthesis from the hydrogenation of carbon dioxide over the CuO/ZnO/Al2O3 catalysts has been reported. Small amount of CO in the raw gases can increase the selectivity and yield of methanol by 38% and 25%, respectively. TPD-MS and TPSR-MS results indicate that CO can suppress the adsorption of CO2 on the sites, which bring about the reverse water-gas shift reaction and hence promote the selectivity of methanol.
