Mn-Cu/TiO2具有较大的比表面积、活性组分与TiO2强烈的相互作用、良好的氧化还原能力以及较高的吸氨能力。故将溶胶凝胶法制备的 Mn-Cu/TiO2催化剂，应用于 NH3低温选择性催化还原(SCR)脱硝技术。为提高该催化剂的活性和抗SO2中毒能力，研究了溶胶凝胶法焙烧温度对Mn-Cu/TiO2催化剂催化性能的影响，并通过吸附 N2能力测试(N2-BET)、X射线衍射试验(XRD)、H2和NH3的化学吸附特性测试(H2-TPR、NH3-TPD)等多种手段对催化剂的理化性能进行表征。研究发现，在400℃下焙烧制备的催化剂拥有最佳脱硝活性和抗SO2中毒能力。

The Mn-Cu/TiO2 prepared by sol-gel method was studied for low temperature selective catalytic reduction (SCR)of NO with NH3.Effects of calcination temperature on catalytic activity of the Mn-Cu/TiO2 catalysts were investigated and discussed.Moreover,properties of the catalysts were characterized by several ways like the N2-BET test,XRD analysis,H2-TPR and NH3-TPD test methods.It was found that the catalyst acclimated at 400 ℃ had the best SCR activity and SO2 resistance performance.Large specific surface area,strong interaction between active components and TiO2 ,good redox ability and high NH3 ad-sorption capacity might be the major reasons for the excellent performance of this catalyst.
