摘要：

Nano IM-5 zeolite was successfully synthesized by hydrothermal method using 1,5-bis(N-methylpyrrolidinium) pentane bromide as structure-directing-agent and polyethylene glycol (PEG) and cetyltrimethylammonium bromide (CTAB) as surfactants. It was investigated by X-ray diffraction, transmission electron microscopy, selected area electron diffraction, N-2 sorption isotherms and solid-state NMR. The results indicate that the PEG and CTAB play an important role during the formation of nano crystal IM-5 zeolite. The aggregates of nano particles with mean size about 35 nm have large surface area than that of micron-sized sample. The solid-state Si-29 NMR spectrum shows that more silanol group defects were observed in the nano crystals. (C) 2011 Elsevier B.V. All rights reserved.
