Abstract

A new method for the synthesis of nanosized ZSM-5 zeolite with the MFI structure in the proton form is reported. The material was synthesized by the hydrothermal-microwave method and characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, atomic force microscopy, low-temperature nitrogen physisorption, thermal desorption of ammonia and solid- state ²⁷Al NMR. The synthesized material is formed by zeolite particles of 30–80 nm in size, which ensures its high specific surface area, pore volume and interparticle porosity.

以质子形式合成纳米级 ZSM-5（MFI）沸石的新方法

报告了一种以质子形式合成具有 MFI 结构的纳米级 ZSM-5 沸石的新方法。该材料采用水热微波法合成，并通过 X 射线衍射、扫描电子显微镜、透射电子显微镜、原子力显微镜、低温氮物理吸附、氨热解吸和固态 27Al NMR 对其进行了表征。合成材料由 30-80 nm 大小的沸石颗粒组成，因此具有较高的比表面积、孔隙率和颗粒间孔隙率。

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
