PROBLEM TO BE SOLVED: To provide a mixed metal oxide catalyst containing vanadium and antimony for ammoxidation of paraffins to unsatured mononitriles, more particularly, propane and isobutane to acrylonitrile and methacrylonitrile, respectively. SOLUTION: The catalyst composition containing the compounds of the formula: VSbaMbOx(wherein V is vanadium, Sb is antimony, M is at least one element selected from the group consisting of magnesium, aluminum, zirconium, silicon, hafnium, titanium, and niobium, (a) is 0.5 to 20, (b) is 2 to 50, (x) is determined by the valence requirements of the other elements present and the vanadium and antimony are separated in the matrix of the oxides of M).
