Conversion of CO2 using renewable hydrogen to produce valuable chemicals has recently become highly attractive. Light olefins are important basic monomers for the production of various commodities. This work developed a bifunctional catalyst composed of ZnO-Y2O3 oxide and SAPO-34 zeolite, which catalyzes the selective hydrogenation of CO2 to light olefins with a selectivity in hydrocarbons reaching 83.9% at a conversion of 27.6% at 390 degrees C. The obtained results demonstrated that CO2 conversion and product distribution are strongly dependent on the oxide composition and structure. This new bimetallic oxide catalyst appears promising for further development of CO2 conversion to other valuable chemicals.
