Influence of the Preparation Method On the V2o5/tio2/sio2 Catalysts in Selective Catalytic Reduction of Nitric-oxide With Ammonia
No full textThe method of deposition of TiO2 on SiO2 and the activation procedure of the silica permits the control of the dispersion of both TiO2 and V2O5 on the surface of the catalysts. Activation of SiO2 by acidic treatment followed by deposition of isopropyl orthotitanate in n-heptane by reflux gives a support with titanium oxide close to monolayer coverage. The dispersion of vanadium oxide and its interaction with the support are then enhanced. The catalytic reduction of nitric oxide with ammonia at two different nitric oxide concentrations is evaluated at 693 and 773 K and correlated with the physicochemical properties of the solids
