Abstract (EN): Vanadium (5 wt%) was incorporated on the Al0.5Ga0.5PO4 support by impregnation and the resulting catalyst, 5V/Al0.5Ga0.5PO4 was characterized by BET surface area, pores distribution, X-ray diffraction, RAMAN spectroscopy and temperature-programmed reduction. Catalytic performances were measured on the propane ammoxidation. Crystalline V2O5 was observed on 5V/Al0.5Ga0.5PO4 catalyst; in addition, the originally amorphous A10.5Gao.5PO(4) Support Crystallises in presence of vanadium. The presence Of V2O5 on Al0.5Ga0.5PO4 enhances the propane conversion and the selectivity to acrylonitrile.
