Supported V-Mo-P oxide catalysts were prepared by wet impregnation method. Catalysts were characterized by FTIR （Fourier transform infrared）, XRD （X-ray diffraction） and TPD （temperature programmed desorption）. The catalytic activity of V-Mo-P oxide catalysts were investigated for vapour phase ammoxidation of 3-picoline. The unsupported catalyst showed 92.1% yield where as V-Mo-P oxide/HZSM-5 showed the highest yield （80.4%） amongst the supported catalysts.展开更多
