| 摘 要： | 从钠基土合成了钛交联粘土(Ti-PILC).以交联粘土作为载体负载Cu,考察了对3H6选择性还原(SCR)NO反应的催化活性.Cu/Ti-PILC显示了很好的低温活性.Cu的负载方法影响催化剂活性.还研究了Ti-PILC负载其他金属(Fe/Ti-PILC,Ce/Ti-PILC,Zn/Ti-PILC,Co/Ti-PILC,Ag/Ti-PILC,Ni/Ti-PILC)催化剂的催化活性.用N2吸附脱附等温线和孔径分布考察了交联过程及铜的负载对粘土结构的影响.

| Abstract: | Ti-pillared clays(Ti-PILCs) were synthesized from Na-montmorillinite.Cu-doped pillared clays were studied as catalysts for selective catalytic reduction(SCR) of NO by propylene.Cu/Ti-PILC showed high activity at relatively low temperatures.The method of copper loading influences the catalytic activity of the catalysts.The following catalysts were also prepared and studied:Fe/Ti-PILC,Ce/Ti-PILC,Zn/Ti-PILC,Co/Ti-PILC,Ag/Ti-PILC and Ni/Ti-PILC.N_2 adsorption/desorption isotherms and pore size analysis were applied to study the influence of the pillaring process and Cu loading on the clay structure. |
