Abstract

The number of surface V=O bonds and the structure of V2O5 on V2O5/TiO2 and V2O5/Al2O3, catalysts with various contents of V2O5 have been determined by using the rectangular pulse technique coupled with infrared measurements of the adsorption of NH3 on the catalysts. Turnover frequencies of the reaction of NO and NH3 in the presence of O2 and the oxidation of benzene have been obtained on the basis of the measured number of surface V=O bonds. It has been found that the former reaction is a structure insensitive reaction whereas the latter one is a structure sensitive reaction. The promotive effects of TiO2 support on the reactions on V2O5 catalyst have also been revealed in terms of the turnover frequency.
