The effect of vanadia loading on the acidic and redox properties of VOx/TiO2 catalyst and their role in thesimultaneous reduction of NO with NH3 and oxidation of o-DCB is studied. Catalyst samples withdifferent proportions of VOx species, ranging from monomerics to V2O5 octahedral crystals have beenprepared. A relationship between VOx species and their acidic and redox properties was found. At lowtemperature, o-DCB is adsorbed mainly on Lewis sites, associated to monomeric species, but at hightemperature, o-DCB and NH3 compete for Brønsted sites associated to polymeric species.
