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C3H6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.
Titanium-crosslinked clays (Ti-PILCs) were synthesized from sodium-based soils, and the catalytic activity for the selective reduction (SCR) of NO with C3H6 was investigated using a cross-linked clay as a support. Cu / Ti-PILC showed good The catalytic activity of Ti-PILC was also studied.At the same time, Ti-PILC loaded with other metals (Fe / Ti-PILC, Ce / Ti-PILC, Zn / Ti- PILC, Ni / Ti-PILC) catalyst.The influence of cross-linking process and copper loading on the clay structure was investigated by N2 adsorption-desorption isotherm and pore size distribution.
