Abstract
Provided is a method for producing a zinc ferrite catalyst, the method comprising: preparing a zinc precursor solution; preparing a ferrite precursor solution; obtaining a first precipitate by bringing the zinc precursor solution into contact with an alkaline solution; obtaining a second precipitate by adding the ferrite precursor solution to the first precipitate; and drying and firing the second precipitate after filtering the second precipitate.
