Abstract

V2O5/AlF3 catalysts with V2O5 loadings ranging from 2 to 15 wt% were prepared by the conventional wet impregnation method, using nonporous AlF3·3H2O sample as the support for impregnating NH4VO3. It was found that the catalysts evolve porous structures upon calcination at 723 K. The influence of V2O5 content was studied on ammoxidation of 3-picoline on the reduced catalysts. The catalyst with 15 wt% V2O5 exhibited the highest selective ammoxidation acitivity towards nicotinonitrile. The XRD and oxygen chemisorption studies revealed that vanadia is in a highly dispersed state in the catalysts.
