Abstract

Abstract

Titania-pillared clay (Ti-PILC) was prepared from butyltitanate, then Mn-CeO_x/Ti-PILC was prepared by impregnating method on the Ti-PILC. The catalysts were characterized by BET, FT-IR, XRD, XPS and NH₃-TPD. The results showed that, the pillaring process was efficient. Active components exist in Mn₂O₃ and CeO₂ in catalyst Mn-CeO_x/Ti-PILC which was a porous mesopore material with high BET surface area(133.7 m²/g), the activity test also indicted that this catalyst had good de-NO_x activity, the removal efficiency could reach 83.1% even at 180 ℃.
