Method for preparing zinc ferrite catalyst

The present disclosure relates to a method for preparing a zinc ferrite catalyst and, more specifically, to a method for preparing a zinc ferrite catalyst, comprising the steps of: (a) dissolving a zinc precursor and an iron (III) precursor in water to prepare a metallic precursor aqueous solution; (b) evaporating the water from the metallic precursor aqueous solution while extracting a catalyst precursor in a solid phase; and (c) baking the extracted catalyst precursor of a solid phase to prepare a zinc ferrite catalyst. As the invention according to the present disclosure can prepare zinc ferrite without going through a step of adjusting pH, the invention has the effects of simplifying the preparation processes and securing reproducibility.
