The invention relates to the technical field of catalysts, and particularly discloses an ammoxidation catalyst as well as a preparation method and application thereof. The ammoxidation reaction catalyst provided by the invention comprises the following components: a carrier, V2O5 and an auxiliary agent, the mass loading amount of the V2O5 in the ammoxidation reaction catalyst is 5-15%, and the carrier is TiO2 modified alpha-Al2O3 or SiO2 modified alpha-Al2O3; in the TiO2 modified alpha-Al2O3, the mass fraction of TiO2 is 1 to 10 percent; in the SiO2 modified alpha-Al2O3, the mass fraction of SiO2 is 1 to 5 percent. The invention also provides application of the ammoxidation catalyst in a process for preparing cyanopyridine by ammoxidation of alkyl pyridine. The ammoxidation catalyst provided by the invention has the advantages of high catalytic efficiency, good stability and reproducibility, and the production cost of preparing cyanopyridine by ammoxidation of alkyl pyridine can be greatly reduced. 本申请涉及催化剂技术
