Title: FERRITE CATALYST FOR OXIDATIVE DEHYDROGENATION REACTION, METHOD FOR PREPARING SAME, AND METHOD FOR PREPARING BUTADIENE BY USING SAME
Abstract:
The present invention relates to a ferrite catalyst for an oxidative dehydrogenation reaction and a method for preparing the same and, more specifically, to: a method for preparing a ferrite catalyst for an oxidative dehydrogenation reaction, comprising, in an epoxide-based sol-gel method, a first sintering step of performing sintering at 70-200 °C, and a second sintering step of performing sintering by increasing the temperature from a temperature higher than 200 °C and lower than or equal to 250 °C to 600-900 °C; and the like. According to the present invention, since an epoxide-based sol-gel method is used, a method for preparing a catalyst is simple, a material comprising a pure spinel structure not including an α-Fe2O3 phase can be obtained, and a large surface area and a macroporous structure is obtained, and thus a catalyst having a higher reactivity than a catalyst prepared by a conventional technique, and the like can be provided.
