Abstract
Vacuum transient pulse and continuous flow investigations on the ammoxidation of propane over VSbxOy (x = 1, 2 and 5) and (VO)2P2O7 catalysts reveal that propene and acrolein are reaction intermediates over both types of oxides. However, the N-insertion step and the formation of total oxidation products proceed significantly different. Short-lived NH3 or NH4 + species are involved in the N-insertion step over V-Sb-O, whereas strongly bound, long-lived NHx species are participating in the reaction on V-P-O. Only lattice oxygen is involved in the hydrocarbon reaction pathway over V-Sb-O, whereas additionally adsorbed oxygen species lead to total oxidation over V-P-O.
