The porous structure of molecular sieves, combined with their chemical composition, makes them uniquely suitable for use as catalysts or catalytic supports. As such, the materials are used in a wide range of chemical reactions, and as components of formulated products.
The shape selectivity of the materials further enhances their chemical usefulness, and exploitation of their 4/5(1). Zeolite Molecular Sieves book. Read reviews from world’s largest community for readers/5(2).
Nanosized zeolite molecular sieves of different Si/Al ratios have been prepared using microwave hydrothermal reactor (MHR) for their greater application in separation and catalytic science. The as-synthesized molecular sieves belong to four different type zeolite families: MFI (infinite and high silica), FAU (moderate silica), LTA (low silica and high alumina), and AFI (alumina rich Cited by: 7.
Molecular Sieves - Science and Technology will be devoted to all kinds of microporous crystalline solids with emphasis on zeolites. Classical alumosilicate zeolites as well as microporous silica will typically be covered; titaniumsilicate, alumophosphates, gallophosphates, silicoalumophosphates, and metalloalumophosphates are also within the scope of the series.
Molecular Sieves - Science and Technology will cover, in a comprehensive manner, the science and technology of zeolites and all related microporous and mesoporous materials.
Authored by renowned experts, the contributions will be grouped together topically in such a way that each volume of the book series will be dealing with a specific sub-field.5/5(1). Robson, editor Templating in molecular sieve synthesis Stephen T.

Molecular sieve, a porous solid, usually a synthetic or a natural zeolite, that separates particles of molecular es are hydrated metal aluminosilicate compounds with well-defined crystalline structures.
The silicate and aluminate groupings form three-dimensional crystal lattices surrounding cavities in which the metal ions and the water molecules are loosely held. Volume 3 deals with the most widely employed techniques for the post-synthesis modificaton of molecular sieves.
Among the topics covered in considerable detail are ion exchange, both in the more conventional variant in aqueous suspension and in the solid-state variant, the various methods for dealumination of zeolites, and the techniques for introducing metallic, ionic, oxidic.
