Abstract

See full text

The present invention relates to a bismuth molybdate-based composite oxide catalyst having a microporous zeolite coating layer on the surface thereof and thus having high selectivity for 1,3-butadiene, a method of preparing the same, and a method of preparing 1,3-butadiene using the same. The catalyst has a microporous zeolite coating layer, and thus enables only gaseous products (light) to selectively pass through the zeolite coating layer, improving selectivity for 1,3-butadiene.
