Abstract

ZnO and nitrogen-doped carbon (NC) overcoated Fe-based catalysts (Fe@NC) were synthesized and evaluated in CO 2 hydrogenation reaction. The Fe@NC exhibited enhanced catalytic activity, stability, and high selectivity toward light olefins and C 5+ hydrocarbons. The olefins over paraffins ratio in the range of C 2 -C 4 increased 24 times from 0.07 to 1.68 compared with the benchmark Fe 3 O 4 catalyst. The evolution of iron species was observed during the hydrogenation reaction. The inactive θ-Fe 3 C phase disappeared, and the active phases for CO 2 hydrogenation, Fe 3 O 4 and Fe 5 C 2 , formed during the hydrogenation reaction. Overcoating the surface of Fe-based catalysts can be used as a useful strategy to modulate the product selectivity toward sustainable production of value-added hydrocarbons from CO 2 .
