In this reaction, bimetallic iron–cobalt catalysts were shown to surpass monometallic iron and cobalt catalysts in terms of catalytic performance. The optimal combination of performance parameters was reached at an iron to cobalt ratio of 3 : 1. The composition and genesis of the active phase in the bimetallic Fe–Co catalyst were identified, and the CO2 hydrogenation mechanism was suggested for an iron-dominated bimetallic catalyst. Using biochar as a support was found to provide an active phase composition favorable for CO2 hydrogenation.</p></abstract><trans-abstract xml:lang="ru"><p>Изучено протекание реакции гидрирования СО<sub>2 на моно- и биметаллических катализаторах на основе биоугля. Показано, что биметаллические железно-кобальтовые катализаторы в процессе гидрирования СО<sub><sub>2 </sub></sub>превосходят по эффективности монометаллические железный и кобальтовый; при этом наилучшее сочетание показателей процесса достигается при соотношении железо : кобальт = 3:1. Определен состав активной фазы биметаллического железно-кобальтового катализатора, генезис ее формирования и предполагаемый механизм протекания процесса гидрирования СО<sub>2</sub> на катализаторе с преобладанием железа в его составе.
