Title : Fast hydrothermal synthesis of nanocrystalline Cs Aluminosilicate zeolites catalysts free of organic template

Abstract:

Zeolites are crystalline aluminosilicates which have well defined channels and cavities. Zeolites are commonly used in ion exchange, catalysis and separation processes due to their unique crystalline structure and tunable surface properties. Subdivision of zeolites into fine particles (1000 bar) and long crystallization time and also, their nanocrystalline form has not been reported so far. Thus, mild and safer synthesis condition with lower heating temperature and pressure remains challenging in Cs-zeolites synthesis. In this presentation, we intend to report the successful synthesis of two types of organotemplate-free nanosized Cs-zeolites using traditional and microwave-assisted hydrothermal techniques. Besides discussing the crystallization for synthesizing the molecular sieves, the properties of zeolites are studied before they are investigated in several catalytic reactions.
