摘要：
The present invention relates to a zinc ferrite catalyst, a method of producing the same, and a method of preparing 1,3-butadiene using the same. Specifically, the present invention relates to a zinc ferrite catalyst which is produced in a pH-adjusted solution using a coprecipitation method, a method of producing the same, and a method of preparing 1,3-butadiene using the same, in which the 1,3-butadiene can be prepared directly using a C4 mixture including n-butene and n-butane through an oxidative dehydrogenation reaction. The present invention is advantageous in that 1,3-butadiene can be obtained at a high yield directly using a C4 fraction without performing an additional process for separating n-butene, as a reactant, from a C4 fraction containing impurities.
