Abstract

A novel F-doped vanadia/titania catalyst has been developed. The catalytic activity of NO removal over this catalyst was significantly promoted by F-doping. Analysis by EPR showed that F-doping facilitated the formation of V⁴⁺ and superoxide ions, and increased the affinity to NO. These made the reaction be progressed through Fast SCR reaction and resulted in the promotion of the NO removal efficiency.
