We prepared V2O5-loaded CVC-TiO2 catalysts by a combination of chemical vapor condensation (CVC) and impregnation method at different calcination temperatures. These catalysts were analyzed for their ability to catalyze NH3-based selective catalytic reduction of NOx. Compared with V2O5 loaded P25-TiO2 (commercial). V2O5/CVC-TiO2 catalysts calcined above 200 A degrees C exhibited better performance towards NOx conversion than that by a commercial catalyst prepared using P25-TiO2 (calcined at 500 A degrees C). In addition, the NOx conversion rate obtained with the sample calcined at 500 A degrees C gave the best result (90 %) at a reaction temperature of 200 A degrees C. From the XPS results, we observed that the V4+/5+ ratio was well balanced when the V2O5 loaded CVC-TiO2 sample was calcined at 500 A(0)C.
