The study of Fe-containing catalytic systems in the carbon dioxide hydrogenation reaction was conducted. A series of systems on the basis of iron oxide Fe2O3 wiśthout the addition of a second component and with the addition of aluminum (Al2O3), cerium (CeO2), zirconium (ZrO2) or silicon (SiO2) oxides was synthesized. Each system was synthesized by two methods, analogous to mesoporous molecular sieves synthesis methods for MCM-41 and SBA-15 with the use of cetyltrimethylammonium bromide and Pluronic 123 templates. The resulting samples had a uniform distribution of components on the surface with a component ratio close to 1:1 and iron oxide crystallite sizes ranging from 7 to 23 nm. The highest activity in the reaction of hydrogenation of carbon dioxide was demonstrated by the sample Fe/Al with Pluronic 123 as a template, the conversion was 11.5%, and the formation of mesopores with a maximum diameter of 15 nm was observed in the sample.
