Abstract

Abstract

A series of Mn/Ti-PILC and Mn-La/Ti-PILC(k=0/1,1/4,1/12 and 1/20)materials were prepared by the method of impregnation. The effects of La doping on Mn/Ti-PILC for low temperature SCR were studied, and also the materials were characterized by BET, H₂-TPR, NH₃-TPD and XRD. It showed that with the doping of La, the reduction temperature of the catalysts lowered, and the redox abilities of the catalysts enhanced. The weak acid on the material surface increased due to the introduction of La. The doping of La was beneficial to the SCR activity. Mn-La/Ti-PILC (k=1/12) showed the best activity.
- La doping,
- Mn/Ti-PILC,
- low temperature SCR
