Abstract

Abstract

Titania-pillared clay (Ti-PILC) was obatined with two different Ti precursors of TiCl₄ and Ti(OC₃H₇)₄; with Ti-PILC as support, Mn-Ce/Ti-PILCs catalysts were prepared through impregnation. The catalytic activity of Mn-Ce/Ti-PILCs in low temperature SCR of NO with NH₃ was investigated. XRD, BET, FT-IR, NH₃-TPD and SEM measurements indicated that the pillaring process can change the structure of the clay; compared with the original clay, the specific surface area, the pore volume and the acidity of Ti-PILCs are increased; meanwhile, Mn-Ce/Ti-PILCs also exhibits higher catalytic activity than Mn-Ce/clay. Moreover, Ti(OC₃H₇)₄ as Ti precursor is more effective in enhancing the catalytic activity of Mn-Ce/Ti-PILCs than TiCl₄.
