Ammoxidation of 3-picoline to nicotinonitrile was investigated on vanadium phosphorus oxide (VPO), and additive atom (Cu, Zr, Mn VPO/SiO 2 and Co) incorporated VPO catalysts under atmospheric pressure and at 673 K. For the purpose of comparison a conventional catalyst was V 2 O 5 ΓMoO 3 /Al 2 O 3 al
A critical assessment of the published data on vanadium phosphorus oxide catalysts is presented. Aspects that are included for discussion include (i,l the nature of the bulk phases present in the active unpromoted catalysts, (ii) the nature of the surface of the active unpromoted catalysts and W the
