摘要：

The synthesis of methanol from CO2 and H-2 in a flow reactor was studied over CuO-ZnO catalysts combined with ZrO2, MgO, Al2O3, or Cr2O3 under a pressure of 13 atm. CuO-ZnO-Al2O3, CuO-ZnO-ZrO2, and CuO-ZnO-MgO showed higher activity and higher selectivity for methanol than did CuO-ZnO. The selectivity for methanol formation became higher as the reaction temperature was lower, or any of the H-2/CO2 ratio, the pressure and the space velocity were higher. On the basis of analyses by XRD, XPS, and ultraviolet diffused reflectance spectroscopy, the active centers of CuO-ZnO-ZrO2 seem to be a Cu+-ZnO species stabilized by ZrO2.
