Ammoxidation catalyst for propylene, manufacturing method of the same catalyst, ammoxidation method using the same catalyst

Abstract

An ammoxidation catalyst includes a metal oxide represented by Chemical Formula 1, wherein a first peak having intensity of A appears in the 2θ range of 26.3=0.5°, and a second peak having intensity of B appears in the 2θ range of 28.3±0.5° in X ray diffraction analysis by CuKα, and an intensity ratio (A/B) of the first peak to the second peak is 1.5 or more: MoxBiaFebAcBdCeDfOy  Chemical Formula 1 wherein in Chemical Formula 1, A and B are different from each other, and each independently, are one or more elements of Ni, Mn, Co, Zn, Mg, Ca, and Ba, C is one or more elements of Li, Na, K, Rb, and Cs, D is one or more elements of Cr, W, B, Al, Ca, and V, a to f, x, and y are respectively mole fractions of each atom or atomic group, a is 0.1 to 7, b is 0.1 to 7, provided that the sum of a and b is 0.1 to 7, c is 0.1 to 10, d is 0.01 to 5, e is 0.1 to 10, f is 0 to 10, x is 11 to 14, y is a value determined by each oxidation number of Mo, Bi, Fe, A, B, C, and D.
