TiO2-SnO2 mixed oxide was prepared by a co-precipitation method and xCeO2/TiO2-SnO2 catalysts were prepared using the impregnation method. The physicochemical properties were investigated by X-ray diffraction (XRD), BET specific surface area measurement, H2 temperature-programmed reduction (H2-TPR), NH3 temperature-programmed desorption (NH3-TPD), high-resolution transmission electron microscopy (HRTEM), and in situ diffuse reflectance infrared spectroscopy (DRIFTS). Meanwhile, their catalytic performance for the selective catalytic reduction of NOx with NH3(NH3-SCR)was tested. It was found that 0.1Ce/TiO2-SnO2 had higher NOx conversion and wider temperature range of 250~350℃. Excess loading of CeO2 could lead to the decrease of specific surface area, redox ability and adsorption capacity of ammonia as well as the shrink of effective catalytic temperature range. NH3-TPD result showed that the adsorption of NH3 in weak acid and medium acid sites were significantly enhanced by CeO2, which was related to the decrease of NH3-SCR reaction temperature. In situ DRIFTS indicated that the strength of Lewis acid sites and Brønsted acid Sites were markedly enhanced for xCeO2/TiO2-SnO2 catalyst. Besides, new Brønsted acid Sites appeared at 1657~1666cm-1 and NH4+ played the dominant role in the SCR reaction.
