Abstract
TiO2 is modified by Fe-doping reduction method to regulate the pore structure of TiO2. When the Fe/Ti molar ratio of 0.05, the Fe–Mn/TiO2 (0.05Fe) catalyst shows an almost 100% NO conversion and N2 selectivity in the range of 170–250 °C. The catalyst exhibits a catalytic activity above 95% even in the presence of SO2 and water. The N2 adsorption–desorption, XRD, H2-TPR, XPS, TG and TEM are used to characterize the catalysts. The results show that the modification of Fe in the TiO2 carrier enlarges the catalysts’ BET surface area, increases the proportion of the high valence states of Mn on the surface, and promotes more defect of the lattice oxygen, and makes TiO2 be coated and protected. All these modification keeps the catalyst having a high and stable SCR activity and sulfur and water resistance at low temperature.
