METHOD FOR PREPARING ZINC FERRITE-BASED CATALYST AND ZINC FERRITE-BASED CATALYST PREPARED THEREBY

摘要

A method for preparing a zinc ferrite-based catalyst comprising: obtaining a precipitate by bringing a metal precursor solution including a zinc precursor, a ferrite precursor, a solution containing an acid and water into contact with a basic aqueous solution; filtering the precipitate; drying the filtered precipitate; and firing the dried precipitate, wherein the solution containing the acid includes one or more of nitric acid (HNO3) and hydrocarbon acid.
