  • Patent number: 10315969
    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.
