Rencently，V-based catalysts have gained increasing importance，and the results were summarized in Table 5.Cha et al.[24]prepared TiO2 nanoparticles by chemical vapor phase condensation（CVC）method，and thensynthesizedV2O5/CVC-TiO2usingthe impregnation method.V2O5/P25-TiO2（a mixed crystal type of Ti O2，and the mass ratio of anatase to rutile is about 71/29）was obtained by loading the same amount of V2O5 on commercial P25-TiO2.As shown in Fig.5[20]，to achieve the NOx conversion rate of 96%，the required operating temperature of the 7wt%V2O5/CVC-TiO2catalyst was about 50℃lower than that of the 5wt%V2O5/CVC-TiO2catalyst.At200℃，the V2O5/CVC-TiO2 catalysts with varying concentrations of V2O5 showed sufficient NOx conversion，while the NOx conversion efficiencies of the V2O5/P25-TiO2catalysts with the same V2O5 concentrations were insufficient.It was proposed that the V2O5/CVC-TiO2catalysts had more anatase phase TiO2，a higher specific surface area，and better dispersion than the V2O5/P25-TiO2 catalysts.The characterizations revealed that V2O5/CVC-TiO2 exhibited larger specific surface area，higher dispersion，and more surface oxygen.
