摘要：

Methanol synthesis from CO2 and H2 was carried out over a Cu/ZnO catalyst (Cu/Zn = 3/7) at atmospheric pressure, and the surface species formed were analyzed by diffuse reflectance FT-IR spectroscopy and temperature programmed desorption method. Two types of formate species and zinc methoxide were formed in the course of the reaction. Zinc methoxide was readily hydrolyzed to methanol. H2O formed through the reverse water gas shift reaction was suggested to be involved in the hydrolysis of zinc methoxide.
