Abstract: Disclosed is a method of making a catalyst precursor by aging an aqueous solution containing the monoperoxovanadium ion, VO(O.sub.2).sup.+, 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(O.sub.2).sup.+ ion is made by reacting H.sub.2 O.sub.2 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 resitant than catalysts of the same empirical formula made by prior art methods.
