Abstract Mo-V-Te-Nb mixed oxides with different compositions were prepared via a surfactant route. Activation of these catalysts confirmed the fact that calcination in air or oxygen leads to the formation of significant amounts of MoO3, inactive in propane ammoxidation, while the calcination in inert atmosphere favored the formation of the TeM3O10 (M=Mo, V, Nb) (I) and Te2M20O57 (M=Mo, V, Nb) (II) phases in a higher extent. The higher propane conversion and selectivity in acrylonitrile were achieved for a Mo:V:Nb:Te=1:0.30:0.15:0.30 calcined in nitrogen at 773K.
