Zeolite Y nanocrystal assembly was synthesized by using cetyltrimethyl ammonium bromide (CTAB) under low gelling and aging temperature in the hydrothermal system. XRD, SEM, N₂ adsorption/desorption isotherms, ²⁹Si and ²⁷Al MAS NMR spectra as well as NH₃-TPD demonstrated that the synthesized zeolite Y is a mesoporous zeolite composed of well-developed nanocrystals with high external surface area, intercrystal mesoporosity and acidity. The conversions of 1,3,5-trimethylbenzene (TMB) and 1,3,5-triisopropylbenzene (TIPB) reflect its superior features for isomerization, selectivity of bulky molecule and catalytic stability.

CTAB在低胶凝和时效温度下合成的纳米Y分子筛分子

十六烷基三甲基溴化铵（CTAB）在低胶凝和老化温度下在水热体系中合成了Y型沸石分子筛。XRD，SEM，N ₂吸附/解吸等温线，²⁹ Si和²⁷ Al MAS NMR光谱以及NH ₃ -TPD证明合成的沸石Y是由发达的纳米晶体组成的介孔沸石，该纳米晶体具有高的外表面积，晶间介孔性和酸度。1,3,5-三甲基苯（TMB）和1,3,5-三异丙基苯（TIPB）的转化反应了其出色的异构化，大分子选择性和催化稳定性。
