为探究钛基柱撑黏土（titania pillared interlayeredclays，Ti-PILC）催化剂低温选择性催化还原NO。的活性，实验通过浸渍法制各了MnOx．CeO2／Ti-PILCs，并测试其低温下脱硝活性，同时将TiOSO4、TiCl4钛源制备的催化剂对比。并运用X射线衍射、透射电镜、N2吸附脱附、氨程序升温脱附等技术对2种催化剂进行表征分析，实验发现以TiOSO4为钛源比以TiCl4为钛源制备的MnO2-CeO2／Ti-PILC具有更好的脱硝活性。以TiOSO4为钛源制备的MnOx-CeO2Ti-PILC在nTi／mclay=15mmol／g时活性最高，在200℃时，其NO脱除效率高达95％以上。

In order to study the selective catalytic reduction （SCR） activity of NOx of the titania pillared interlayered clays （Ti-PILC） related catalysts, MnOx-CeO2 were introduced to Ti-pillared interlayered clays with different titania precursors including TiOSO4 and TiCl4 by impregnating method. MnOx-CeO2/ Ti-PILCs were studied as catalysts of selective catalytic reduction of NO with NH3 at low temperature. The obtained catalysts were characterized by X-ray diffraction （XRD）, transmission electron microscope （TEM）, N2 adsorption-desorption and NH3-temperature programmed desorption measurements. The results showed that MnOx- CeOJTi-PILC prepared with TiOSO4 showed better de-NOx activity than that with TiCI4. The de-NO efficiency of MnOx-CeO2/Ti-PILC prepared with the precursor TiOSO4 is higher than 95% at 200℃, and the best nTi/melay was 15 mmol/g.
