Product distributions from CO2 hydrogenation over Fe-based catalysts: a FeK, and b FeKMg. Bar charts show hydrocarbon selectivity versus carbon number. c CO2 conversion and product selectivity for Fe7C3-K with varying Mg levels. d Comparison of the catalytic performance of Fe7C3 with that of other previously reported catalysts (These catalysts cited from 1 to 23 are shown in supplementary Tables 8, high-value olefins: olefins of all carbon numbers). e Stability test of the Fe7C3-KMg catalyst. (Reaction conditions: 0.10 g of catalyst, 340 °C, 2.0 MPa, H2/CO2 = 3, GHSV = 6 L·gcat−1·h−1).
