  • Low-temperature selective catalytic reduction (SCR) catalysts were prepared by step wise blending method with TiO2, TiO2-Al2O3 and TiO2-SiO2 as support and Mn as active component, Ce as promoter. The effects of doping Al2O3 and SiO2 to TiO2 support on NOx removal activity of the catalysts were systematically investigated. The catalysts were characterized by XRD, BET surface area, SEM, H2-TPR and NH3-TPD. It was found that the specific surface area, pore structure parameters and surface pore structure morphology of the catalysts were improved and the TiO2 crystallinity of Mn-Ce/TiO2-Al2O3 and Mn-Ce/TiO2-SiO2 catalysts were reduced to some extent by doping SiO2, Al2O3 on TiO2 support respectively. The low temperature reduction peak area, acid type and acidity of catalysts surface were improved significantlybydoping modification. All of these were beneficial to enhance the denitration activity of the catalysts. The denitration activity of the catalysts was increased to a great extent by doping SiO2 and Al2O3 on TiO2 support respectively, the order of SCR activity of three kinds of catalysts above was:Mn-Ce/TiO2-SiO2 > Mn-Ce/TiO2-Al2O3 > Mn-Ce/TiO2 when the SCR reaction temperature was in the range of 80-140℃.
