Abstract

The catalytic activity of Fe–Co catalysts applied on carbon fibers of various morphologies was studied in the CO2 methanation reaction The catalysts produced by applying the active mass on the cleaned oxygenated or cleaned reduced carbon fibers exhibited a lower activity. It was demonstrated by the SEM method that an increase of the amount of oxygen-containing functional groups on the carrier surface has a negative influence on the catalytic activity of the samples in the methanation reaction and hinders the processes of metal nitrates adjoining the carrier surface and the reduction of the active mass during the synthesis of catalysts. The sample Fe: Co = 86: 14 applied on the non-modified cleaned carbon fibers (T 65 = 390°C, with \({S_{C{H_4}}}\)) showed the greatest activity in the CO2 methanation reaction.
