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