Abstract—A F- and W- doped V ₂ O₅/TiO ₂ has been developed used for low-temperature selective catalytic reduction (SCR) of NO with ammonia. The experimental results showed that NO conversion could be improved by doping F and W, NH   ₃    and O  ₂   were important for the NO adsorption over the VWTiF catalystand the VWTiF catalyst had a  good SO ₂  and H₂  O resistance.  

Index Terms—F- and W- doped V ₂ O₅/T i O_2 , SCR.
