ABSTRACT OF THE DISCLOSURE Disclosed herein are catalysts useful for oxi- dation and ammoxidation of hydrocarbons. Such catalysts have the empirical formula Image wherein a is 0.5-2, b is 0.01-3, c is 0.01-10, d is 0-0.5 and x is selected to satisfy the valence requirements of the other elements present. In such catalysts, M is one or more elements selected from Groups I-A, II-A, III-A, V-A. VI-A, I-B, IV-B, VI-B and VII-B of the Periodic Table. Catalysts according to the invention are pre- pared by forming a slurry of vanadium antimonate compon- ent, a bismuth molybdate component, and optionally the compound M and/or a support material, drying the slurry, and calcining to form the catalyst. Such catalysts are specifically useful for pro- duction of acrylonitrile from propylene, ammonia and an oxygen-containing gas.
