Abstract: This study investigates composite metal-polymer catalysts for converting CO2 into valuable petrochemical products. A series of composite catalysts based on Fe, Co, and polyvinyl alcohol (PVA) were synthesized via the organic matrix method. and their physicochemical properties and catalytic performance were evaluated. X-ray diffraction (XRD) analysis and Fourier transform infrared (FTIR) spectroscopy of the reaction products revealed that the synthesis process facilitates the formation of active catalytic phases—Fe3O4, CoO, and (CoFe2)O4— stabilized within a carbon matrix featuring a developed system of polyconjugated bonds. The resulting composites exhibit high catalytic activity in CO2 hydrogenation at 260–380°C without requiring preactivation. Notably, the bimetallic Fe–Co catalysts achieved a CO2 conversion increase from 7 to 23% even at 260°C. [ABSTRACT FROM AUTHOR]
