Реферат: The catalytic conversion of carbon dioxide toward methanol is of great practical and scientific importance in the concept of reducing CO2 emissions. Moreover, it can partially solve the problem of human dependence on non-renewable resources. The development of selective and active catalysts for CO2 hydrogenation is a key point due to the strong thermodynamic limitations and chemical stability of CO2. In this work, the influence of the nature of the mesoporous supports, as well as the method of introducing the active component, on the catalytic properties of Cu-Zn catalysts in the CO2 hydrogenation to methanol was investigated. A series of bimetallic Cu-Zn catalysts deposited on mesoporous MCM-41 and SBA-15 supports were prepared by two methods: encapsulation and incipient wetness impregnation. The obtained catalysts were characterized by N2 adsorption, XRD, SEM-EDX, TG-DTA methods. The highest CO2 conversion and methanol space-time yield were observed over the encapsulated Cu-Zn catalyst based on the MCM-41 support. The optimal process temperature was 280 ​°C, at which a high selectivity of 92 ​% methanol formation was achieved while maintaining the best CO2 conversion. The study demonstrates the prospects of using bimetallic Cu-Zn catalysts encapsulated in MCM-41 for direct CO2 hydrogenation for ​« ​green ​» ​methanol production.
