Аннотация: The catalytic properties of Cu–Zn catalysts are investigated on such commercial supports as Al2O3, SiO2, ZrO2(La), TiO2, ZnO, and activated carbon in the reaction of CO2 hydrogenation with the production of methanol. CuZn/Al2O3 catalyst displays the highest conversion of CO2. The highest selectivities toward methanol (99 and 97.5%) are observed for CuZn/ZrO2(La) and CuZn/SiO2 catalysts, respectively, while high values of selectivity toward CH3OH (90–95%) are achieved in the 175–275°C range of temperatures. The highest methanol productivity is 547 g/(kgkat h) on catalyst CuZn/ZrO2(La). The synthesized catalysts are studied via low-temperature nitrogen adsorption, X-ray diffraction, and SEM-EDX.
