Catalytic behaviour of M1, M2, and M1/M2 physical mixtures of the Mo-V-Nb-Te-oxide system in propane and propene ammoxidation
Essentially pure orthorhombic M1 and pseudo-hexagonal M2 phases were prepared using the precursor method. Consistent with literature the M1 phase was shown to be effective for propane ammoxidation to acrylonitrile while the M2 phase was essentially inert for propane activation. Both phases convert propene efficiently to acrylonitrile. Both phases show a significant selectivity dependence on the am
