Micro/mesoporous composites based on colloidal zeolite grown in mesoporous matrix
被引频次: 8 (来自 Web of Science)

摘要: Composite materials containing micro- and mesopores are prepared under instantaneous hydrothermal treatment of initial solutions generally used for zeolite Beta and precursor solutions for mesoporous Al-MCM-41 material. The resulting composites are compared with pure, highly crystalline colloidal microporous Beta zeolite and hexagonally ordered mesostructured samples. The porosity and morphological features of the composite materials are influenced by the conditions of hydrothermal synthesis of the initial colloidal solutions used for the preparation of Beta seeds, as well as by the conditions of the synchronized crystallization of the final composites. The embedding of Beta seeds in the mesoporous silica matrix is possible via immediate heating of mesoporous precursor solutions with Beta seeds primarily formed. The composite materials contain either microcrystalline Beta nanodomains with sizes of about 5 - 10 nm surrounded by mesoporous material or defined Beta nanocrystals ( 20 - 40 nm), and at the same time connected with mesostructured material. The presence of highly crosslinked silicate framework walls and tetrahedrally coordinated aluminum in the composite material are confirmed by solid-state Si-29 and Al-27 MAS NMR spectroscopy. The concentration of Bronsted acid sites in the micro/mesoporous com
一切皆有可能!

谢谢您,不过我想要的不是介孔分子筛方面的文献,而是具有介孔-微孔复合孔结构的沸石分子的制备相关文献综述,不过还是要谢谢您的回复。

cnki上不有的是嘛。。。在企业不方便查的 可以找学校的师妹师弟老师帮查
哥把百度杀了,因为这货知道的太多了。
