A F-doped V2O5–WO3/TiO2has been developed for low-temperature selective catalytic reduction (SCR) of NO with NH3. The aim of this novel design was to improve the activity of a catalyst with low WO3loading. Analysis by PL spectra, XRD, XPS and EPR showed that F doping improved the interaction of WO3with TiO2by oxygen vacancies to facilitate the formation of W5+that was important to improve the formation of superoxide ions. The experimental results showed that NO conversion could be improved by F doping and V1W3TiF1.35showed the highest NO removal efficiency in SCR reaction at low temperatures.
