Abstract

CuO/MCM-41 catalyst was synthesized by a simple method with the modification of ethylene glycol (EG) and characterized by powder X-ray diffraction (XRD), nitrogen sorption, scanning electron microscopy (SEM) and transmission electron microscope (SEM). Its catalytic performance in the hydrogenation of CO₂ to methanol was also investigated. The results indicated that the as-synthesized CuO/MCM-41-EG catalyst took the properties of high dispersion, small particle size and high surface area, and then showed catalytic performance for the CO₂ hydrogenation to methanol. At the optimum reaction temperature of 240 °C, the CuO/MCM-41-EG catalyst gave 15% CO₂ conversion and 35% methanol selectivity.
