摘要

The disordered mesoporous material, KIT-1, has been successfully synthesized in a facile route in the presence of mixtures of cteyltrimethylammonium bromide (CTAB) and dodcyl-4-aza-1-azaniabicyclo [2.2.2]octane bromide ([C(12)dabco]Br) ionic liquid as dual template for the first time. KIT-1 was characterized via FT-IR, XRD, N-2 adsorption-desorption analysis, SEM and high-resolution TEM. The synthesized KIT-1 showed total BET surface area of 1012 m(2) g(-1), it shows slight decrease comparing to MCM-41 with BET surface area of 1029 m(2) g(-1). The XRD pattern of KIT-1 shows that all the diffractions are weakened and broadened compare to MCM-41. The TEM image of KIT-1 exhibits that the pore structure is a disordered network of short wormlike pores of mesopores and interconnecting to each other in a three-dimensional disordered way with relatively uniform pore size. A possible mechanism was proposed to explain the effect of ionic liquid in formation of KIT-1 sample.
