Abstract
Provided are a method of preparing a multicomponent bismuth-molybdenum composite metal oxide catalyst, and a multicomponent bismuth-molybdenum composite metal oxide catalyst prepared thereby. According to the preparation method, since the almost same structure as that of a typical quaternary bismuth-molybdenum catalyst may be obtained by performing two-step co-precipitation, i.e., primary and secondary co-precipitation, of metal components constituting the catalyst, the reduction of catalytic activity due to the deformation of the structure of the catalyst may be suppressed. Also, since the multicomponent bismuth-molybdenum composite metal oxide catalyst may adjust the number of lattice oxygens consumed during a reaction to increase the catalytic activity, the multicomponent bismuth-molybdenum composite metal oxide catalyst may reduce the formation of by-products and may improve the conversion rate of reactant and the yield of desired product in a catalytic reaction process using the above catalyst, particularly, a catalytic reaction process under a relatively low temperature condition.
