Hydrogenation of CO₂ over Biochar-Supported Catalysts

Svidersky, S. A. / Dement’eva, O. S. / Ivantsov, M. I. / Grabchak, A. A. / Kulikova, M. V. / Maximov, A. L.

The study investigates hydrogenation of CO₂ over mono- and bimetallic catalysts supported on biochar. 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.
