Among the catalysts, the sample prepared by sol–gel method had the best performance on both activity and SO2 resistance. From the results of thermo gravimetric analysis (TGA), X-ray diffraction (XRD), transmission electron microscopyvailable online 13 June 2008 eywords: nOx/TiO2 ol–gel mpregnation (TEM) and X-ray photoelectron spectrum (XPS), it was known that manganese oxides and titania existed in different phase in the samples prepared by three methods. Strong interaction, large surface area, high concentration of hydroxyl groups, high concentration of amorphousMn on the surfacemight be themain reasons for the excellent performance of the catalysts. ? 2008 Elsevier B.V.

Introduction In recent years, there is an interest in developing apotential low- emperature (353–533K) SCR catalyst, and then the catalyst bed an be moved downstream of the desulfurization scrubber and/or articulate control device, wheremost of sulfur dioxide and dust is emoved and the deactivation is weakened. Manganese oxides attract interest as catalysts since they contain arious types of labile oxygen, which are necessary to complete cataly
