Abstract: A method of hydrogenating carbon dioxide, including contacting carbon dioxide and hydrogen with an iron-based catalyst to form a liquid and a gas. The liquid includes CnH2n, CnH2n+2, or a combination thereof and water, wherein n is 5 to 18. The gas includes CH4, CmH2m, CmH2m+2, or a combination thereof, hydrogen, and carbon dioxide, wherein m is 2 to 9. The iron-based catalyst includes 70 mol % to 97 mol % of porous FeO(OH)x (wherein 1
