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. (c) 2007 Elsevier B.V. All rights reserved.
