Document Type and Number:
WIPO Patent Application WO/2019/199042
Kind Code:
A1
Abstract:
The present specification pertains to a method for producing a metal complex catalyst, and a metal complex catalyst produced by the method, the method comprising the steps of: (A) obtaining a precipitate by contacting a metal precursor solution, which contains a zinc (Zn) precursor, a ferrite (Fe) precursor, and water, with a basic aqueous solution; (B) obtaining a zinc ferrite catalyst by filtering and calcining the precipitate; and (C) impregnating the zinc ferrite catalyst with an acid.
