The direct ammoxidation of propane to acrylonitrile is a potential route for acrylonitrile production with great economic attraction. The reaction mechanism of propane ammoxidation and all potential reaction routes are discussed. Ideas in the catalyst design for propane ammoxidation and several kinds of catalysts for the direct synthesis of acrylonitrile from propane are introduced. Antimonates and molybdates are summarized in detail between these catalysts for propane ammoxidation. The structures of their active phases in these two catalysts, the main factors which can affect the formation of the active phases of catalysts, and the relationships among the structures of the catalysts and their catalytic reaction/selectivity for propane ammoxidation are illustrated.
