Abstract: This invention relates to a method of preparing multicomponent bismuth molybdate catalysts composed of four metal components and a method of preparing 1,3-butadiene using the catalyst, and particularly, to multicomponent bismuth molybdate catalysts composed of a divalent cationic metal, a trivalent cationic metal, bismuth and molybdenum, a preparation method thereof, and a method of preparing 1,3-butadiene from a C4 mixture including n-butene and n-butane using oxidative dehydrogenation. According to this invention, it is possible to prepare catalysts having high activity for the preparation process of 1,3-butadiene only using four metal components as shown through systematic investigation of types and ratios of metal components, unlike conventional multicomponent metal oxide catalysts having a complicated composition of metal components.
