Abstract

Developing sustainable routes for the synthesis of zeolites is still a vital and challenging task in zeolite scientific community. One of the typical examples is sustainable synthesis of aluminosilicate EU-1 zeolite, which is not very efficient and environmental-unfriendly under hydrothermal condition due to the use of a large amount of water as solvent. Herein, we report a sustainable synthesis route for aluminosilicate EU-1 zeolite without the use of solvent for the first time. The physicochemical properties of the obtained EU-1 zeolite are characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetry-differential thermal analysis (TG-DTA), N sorption, inductively coupled plasma (ICP) analysis, and solid nuclear magnetic resonance (NMR), which show the product has high crystallinity, uniform morphology, large BET surface area, and four-coordinated aluminum species. Moreover, the impact of synthesis conditions is investigated in detail. The sustainable synthesis of aluminosilicate EU-1 zeolite under solvent-free.

摘要

开发沸石的可持续合成路线仍然是沸石科学界的一个重要而具有挑战性的任务。其中一个典型的例子是在水热条件下合成硅铝酸盐 EU-1 沸石，由于使用大量的水作为溶剂，其效率不高且不环保。本文首次报道了一种无溶剂合成硅铝酸盐 EU-1 沸石的可持续合成路线。通过粉末 X 射线衍射（XRD）、扫描电子显微镜（SEM）、热重-差热分析（TG-DTA）、N 吸附、电感耦合等离子体（ICP）分析和固体核磁共振（NMR）对所得 EU-1 沸石的物理化学性质进行了表征，结果表明该产物具有高结晶度、均匀的形态、大的 BET 表面积和四配位的铝物种。此外，还详细研究了合成条件的影响。在无溶剂条件下可持续合成硅铝酸盐 EU-1 沸石。
