• FeC x catalysts (Fe-CN-Py) were synthesized by co-pyrolyzing the mixture of iron nitrate and a CN source (melamine, bulk g-C 3 N 4 (b-C 3 N 4 ), or defective g-C 3 N 4 (d-C 3 N 4 )). The physicochemical properties of Fe-CN-Py catalysts and their activities of CO 2 hydrogenation to light hydrocarbon (C 2 -C 6 ) were analyzed. The results indicated that Fe-d-C 3 N 4 -(0.3)-Py is the most promising with the highest CO 2 conversion (47.2%), olefin yield (10.8%), and olefin space-time yield (STY = 4.5 µmol olefin/s/g Fe ). The promising activity of Fe-d-C 3 N 4 -(0.3)-Py was attributed to its high concentration of surface FeC x . The correlation between surface FeC x and the STY of hydrocarbons and olefins was established.
