采用浸渍法制备Cu-Ti-PILC和Pd/Cu-Ti-PILC催化剂,结合X射线衍射谱( XRD)、程序升温还原( TPR)、NO程序升温脱附( NO-TPD)、丙烯选择催化还原NO( C3 H6-SCR)研究Pd组分对Cu-Ti-PILC催化剂结构和催化还原NO能力的影响。 XRD结果表明,Pd物种破坏了蒙脱土的层间排列但未改变Ti-PILC的层间距；TPR结果表明, Pd改变Cu-Ti-PILC催化剂表面上铜物种的还原性能；NO-TPD结果表明,Pd组分提高催化剂化学吸附NO；C3 H6-SCR结果显示Pd物种能够提高Cu-Ti-PILC催化效果。

Cu-Ti-PILC and Pd/Cu-Ti-PILC catalysts were prepared using ion exchange strategy and used for selective catalytic reduction ( SCR ) of NO by propylene. The influences of Pd species on catalyst structure and catalytic performance were investigated by XRD,TPR,NO-TPD and C3 H6-SCR. The results of XRD showed that Pd destroyed interlayer arrangement of clay and did not change the interlayer distance of Ti-PILC. TPR results showed that Pd changed the redox of Cu species. NO-TPD results showed that Pd increased the nitrate amount. The results of C3 H6-SCR showed that Pd improved the N2 yield over Cu-Ti-PILC.
