Effect of V2O5 loading of V2O5/TiO2 catalysts prepared via CVC and impregnation methods on NOx removal

- 7 wt.% V2O5/CVC-TiO2 catalysts resulted in optimal NOx conversion at 200 °C (96%).
- Amorphous V2O5 was well-dispersed onto the CVC-TiO2 surface.
- Increased loading resulted in more polymeric and less monomeric V2O5.
- V2O5 had more V4+/5+ and acid sites (V5+OH) on CVC-TiO2 than on P25-TiO2.
- H2-consumption of V2O5/CVC-TiO2 was 2.42 times that of the commercial catalyst.
