Zusammenfassung:A method for preparing a zinc ferrite-based catalyst according to an exemplary embodiment of the present application comprises: obtaining a precipitate by bringing a metal precursor solution comprising a zinc precursor, a ferrite precursor, an acid solution, and water into contact with a basic aqueous solution; and filtering the precipitate, and then drying the filtered precipitate, and firing the dried precipitate, in which the acid solution comprises one or more of nitric acid (HNO3); and hydrocarbon acid.
