• Excellent SO2 durability at low temperature is obtained with SO42 − MnCoCe/T/S.
• The catalyst exhibits best NOx conversion efficiency of 99.5% at 250 °C.
• The NOx conversion does not decrease after repeatedly used for 8 times.
• Sulfating and T/S support increase surface area and decrease crystallinity.
The catalysts SO42 − Mn–Co–Ce/TiO2/SiO2 were investigated for the low-temperature SCR of NO with NH3 in the presence of SO2. An excellent SO2 durability at low temperature was obtained with the catalyst used TiO2/SiO2 as support and modified with SO42 −. The catalyst sulfated with 0.1 mol/L H2SO4 solution and then calcined at 300 °C exhibited the best NOx conversion efficiency of 99.5% at 250 °C in the presence of 50 ppm SO2. The conversion efficiency did not decrease after repeatedly used for 8 times.
