The CO2 hydrogenation to high valuable chemicals have received considerable attention via Fischer-Tropsch reaction over iron-based catalysts. In this work, iron-metal oxides (FeMOx) were prepared, characterized, and examined to produce liquid hydrocarbons (C5+) from CO2 hydrogenation. The superior performance was obtained using iron-metal oxides (FeMOx). The iron oxide shows 4.8% CO2 conversion and 0.7% C5+ yield using H2/CO2 ratio of 3:1 at space velocity of 4000 mLg-1h-1. On the other hand, with the iron-metal oxides (FeMOx) catalysts CO2 conversion drastically increases to 34.6% and C5+ yield increases to 14.3%. The considerable increase in the hydrocarbon selectivity and CO2 conversion, with the addition of metal in iron catalysts also enhances the iron carbides (Fe5C2) phase which facilities the chain-growth reactions.
