Abstract
A series of zeolites ZSM-5 has been synthesized in hydrothermal conditions at 160°C by varying the time of HT treatment with the following molar compositions of the precursor gel: 1.0 SiO2 : 0.01 Al2O3 : 0.2 ТPAОН : 0.05 Na2O : 50 H2O : 4.0 EtOH. Materials have been characterized by X-ray diffraction, transmission electron microscopy and nitrogen adsorption measurements. We have succeeded to synthesize ZSM-5 crystals with metastable aggregate-like morphology reproducibly and to follow their evolution during HT treatment.

聚集体状 ZSM-5 晶体的演变
摘要
一系列沸石 ZSM-5 在 160°C 的水热条件下通过改变 HT 处理的时间与以下摩尔组成的前体凝胶合成: 1.0 SiO 2 : 0.01 Al 2 O 3 : 0.2 ТPAОН : 0.05 Na 2 O:50 H 2 O:4.0 EtOH。材料已通过 X 射线衍射、透射电子显微镜和氮吸附测量进行了表征。我们成功地合成了具有亚稳态聚集体样形态的 ZSM-5 晶体,并在 HT 处理过程中跟踪它们的演变。
