    Abstract: Disclosed is a method of making a catalyst precursor by aging an aqueous solution containing the monoperoxovanadium ion, VO(O₂)⁺, until a vanadium-­containing sol or gel is formed, and reacting said vanadium while in said aqueous sol or gel form, with an antimony compound that contains Sb having a valence of 3. In one embodiment, the VO(O₂)⁺ ion is made by reacting H₂O₂ with a vanadium compound.
    Also disclosed is making a catalyst by drying and calcining such precursor. When the drying is effected by spray drying a microspheroidal catalyst is produced. The catalysts useful for ammoxidation of propane are more attrition resistant than catalysts of the same empirical formula made by prior art methods.
