Abstract
A method for preparing a metal complex catalyst by (A) obtaining a precipitate by bringing a metal precursor solution comprising a zinc (Zn) precursor, a ferrite (Fe) precursor, and water into contact with a basic aqueous solution; (B) obtaining a zinc ferrite catalyst by filtering and calcining the precipitate; and (C) supporting an acid onto the zinc ferrite catalyst, and a metal complex catalyst prepared thereby.
