Title
The influence of F and Cl on Mn/TiO2 catalyst for selective catalytic reduction of NO with NH3: A comparative study
Abstract

•Both of Cl and F have a poisoning effect on Mn/TiO2 catalyst, and the poisoning effect of Cl is more serious.•The addition of F or Cl on Mn/TiO2 catalyst makes Mn species less reducible.•The doping of F or Cl would decrease the concentrations of surface Mn4 + and chemisorbed oxygen.

The effect of F and Cl on Mn/TiO2 catalyst for selective catalytic reduction of NO with NH3 was investigated in this study. It was found that the doping of F or Cl has a deactivation effect on Mn/TiO2 catalyst. And the poisoning effect of Cl is more serious than that of F. The characterization results showed that the decrease of BET surface area, the increase of crystallinity, the reduced reducibility and surface acidity, and the decreased concentrations of surface Mn4 + and chemisorbed oxygen should be responsible for the deactivation of Mn/TiO2 catalyst by the doping of F or Cl.
