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.
Claims12
A method for preparing a metal complex catalyst, the method comprising:
- (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, wherein a content of the acid is 0.05 wt % to 0.2 wt % based on 100 weight % of the zinc ferrite catalyst, and calcining the zinc ferrite catalyst onto which the acid is supported.
A metal complex catalyst comprising a zinc ferrite catalyst and an acid, wherein the acid is present in an amount of 0.05 wt % to 0.2 wt % based on 100 weight % of the zinc ferrite catalyst.
