A catalyst for acrylonitrile production, which is represented by the following general formula. FeaSbbCcDdTeeCofGgXxYyZzOh(SiO2)i (In the formula, C is selected from among Cu and Ni; D is selected from among Mo, W and V; G is selected from among P and B; X is selected from the group consisting of Sn, Ti, Zr, Nb, Ta, Ru, Pd, Ag, Al, Ga, In, Ta, Ge, As, Bi, La, Ce, Pr, Nd and Sm; Y is selected from the group consisting of Mg, Ca, Sr, Ba, Mn, Zn and Pb; Z is selected from the group consisting of Li, Na, K, Rb and Cs; a-i and x-z represent atomic ratios of respective elements (in the case of SiO2, that of silicon); and when a = 10, b = 5-60, c = 1-8, d = 0.1-4, e = 0.1-5, f = 0.1-4.5, g = 0.1-5, x = 0-5, y = 0-5, z = 0-2, i = 10-200, h is the atomic ratio of necessary oxygen, and (a + f)/b is from 0.50 to 0.60 (inclusive).) |
