Hydrogenation of CO2 to methanol over Cu-ZnO/Al2O3 catalysts prepared by co-precipitation method with ultrasound irradiation
Introduction The greenhouse effect is a threat to the living environment of mankind. The conversion of CO2 that would otherwise get into the atmosphere into useful chemicals, e.g. methanol, is an attractive way to protect the global environment, since CO2 is not only an important greenhouse gas but a carbon resource. Moreover, methanol itself is a useful raw chemical and solvent. Several modifications have been used to improve conventional Cu-ZnO/Al2O3 methanol synthesis catalysts. The key is to keep a high dispersion of the Cu/Zn crystallites. Consequently, the present study was undertaken to assess the efficiency of a new preparation method based on co-precipitation under ultrasound irradiation in improving the physicochemical properties of the Cu-ZnO/Al2O3 catalyst.
