Abstract

A novel V₂O₅/TiO₂ composite material was synthesized by chemical vapor condensation (CVC) method. It exhibited nearly 100% NH₃-SCR activity at 250 C. Characterization results show that the V₂O₅/TiO₂ material prepared by CVC had a higher specific surface area compared to that of V₂O₅ supported on TiO₂ (P25) and its commercially available equivalent material. In particular, V₂O₅/TiO₂ material prepared by CVC had well-balanced V⁴⁺/V⁵⁺ ratio, resulting in high deNO_x performance.
