Abstract:
A catalyst comprising a mixed metal oxide having the empirical formulaMoaVbNcXdZeOf whereinN is at least one element selected from the group consisting of Te, Sb, Sn, Ge and Bi, X is at least one element selected from the group consisting of Nb, Ta, Ti, Al, Zr, Cr, Mn, Fe, Ru, Co, Rh, Ni, Pt, B, In, As, Li, Na, K, Rb, Cs, Fr, Be, Mg, Ca, Sr, Ba, Hf, Pb, P, Pm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu, La, Sc, Au, Ag, Pd, Ga, Pr, Re, Ir, Nd, Y, Sm, Tb, W, Ce, Cu and Zn, and Z is selected from the group consisting of Se and Bi; and wherein, when a=1, b=0.01 to 1.0, c=0.01 to 1.0, d=0.01 to 1.0, e=0.01 to 0.1 and f is dependent on the oxidation state of the other elements;with the proviso that, when Z is Se, Sb and Ga are not simultaneously present in the mixed metal oxide.
