Abstract

A ferrite catalyst for oxidative dehydrogenation and a method of preparing the same. The ferrite catalyst is prepared using an epoxide-based sol-gel method, wherein a step of burning includes a first burning step, in which burning is performed at a temperature of 70 to 200° C.; and a second burning step, in which burning is performed after the temperature is raised from a temperature in the range of greater than 200° C. to 250° C. to a temperature in the range of 600 to 900° C.
