英文摘要	A series of CeO2-WO3/20%ATP-TiO2 catalysts were synthesized, of which attapulgite (ATP) was modified by different methods. Notably, after ATP was dissociated and acidified, the catalyst synthesized by the impregnation method exhibited satisfactory performance for selective catalytic reduction (SCR) NOx with NH3. In more detail, the NO conversion could reach to 88% at 240 degrees C and maintain above 93% in the temperature range of 280-400 degrees C. Subsequently, the NO conversion of the best catalyst could keep above 80% after introducing H2O and SO2, so this catalyst also had strong tolerance to H2O and SO2 performance. Besides, the results of XRD, XPS, TEM characterizations suggested that the high dispersion of active species cerium and tungsten on the surface of ATP, which played an important role in improving the SCR performance of the catalyst. In short, the surface dissociation and surface acidification of a small amount of ATP carrier can improve the catalyst catalytic performance, so it will have a broad application prospect in SCR reaction.
