We report the incorporation of Ga, Fe, and W, well-known activity and selectivity promoters in lower alkane activation, into Te-free Mo–V–O M1 phase in order to improve its stability under propane ammoxidation conditions. The Mo–V–M–O (M = W, Fe, Ga) M1 phases displayed improved stability as compared to the parent Mo–V–Te–O M1 phase due to higher Tammann temperatures of M oxides and activity for direct conversion of propane to propene and acrylonitrile.
