Abstract
The influence of nitridation temperature on aluminovanadate catalyst synthesized by coprecipitation has been studied by XPS. This work presents the change in the vanadium environment (from the emission V2p(3/2)) and the evolution of the nitrogen multi-components signal (from the emission N1s). The results show that vanadium is present in the oxynitride in two forms: a reduced oxidation state VOx and a nitride V3+ species and that nitride nitrogen appears from 773 K.
