Abstract
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 ([C12dabco]Br) ionic liquid as dual template for the first time. KIT-1 was characterized via FT-IR, XRD, N2 adsorption-desorption analysis, SEM and high-resolution TEM. The synthesized KIT-1 showed total BET surface area of 1012 m2 g-1, it shows slight decrease comparing to MCM-41 with BET surface area of 1029 m2 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.
