摘要：
Mn/TiO2, Mn-Ce/TiO2, and Sb-modified Mn-Ce-Sb-x/TiO2 catalysts were prepared by the impregnation method. The catalysts were characterized by BET, XRD, XPS, SEM, NH3-TPD, FTIR, TG-DSC, H-2-TPR, and the SCR (Selective Catalytic Reduction) activity, and investigated by SO2, and H2O resistance between 90 degrees C and 220 degrees C. Results showed that the molar ratio of Sb/Mn is 0.2, the catalytic activity of Mn-Ce-Sb-0.2/TiO2 can reach 94% of NO conversion rate at 120 degrees C. Meanwhile, Mn-Ce-Sb-0.2/TiO2 has the best SO2 and H2O resistance. Characterization results demonstrated that the modification of Sb can decrease the crystallinity of the Mn element, while Sb can inhibit the formation of sulfate and reduce the poisonous effect of SO2 on the catalyst.
