METHOD FOR MANUFACTURING ZINC FERRITE CATALYST AND ZINC FERRITE CATALYST MANUFACTURED THEREBY

WIPO Patent Application WO/2019/132392

A1

The present specification relates to a method for manufacturing a zinc ferrite catalyst, comprising the steps of: preparing a zinc precursor solution; preparing a ferrite precursor solution; bringing the zinc precursor solution into contact with an alkaline solution to obtain a first precipitate; adding the ferrite precursor solution to the first precipitate to obtain a second precipitate; and filtering the second precipitate, followed by drying and firing.
