Microporous alumosilicates

The aim of this work is testing of SERS-activity of metal-containing microporous alumosilicates or zeolites. Porous structure of zeolite skeletons caused by coupling of tetrahedral [Si04] and [AIO4] building units is a unique basis for stabilization of a super-lattice of mono-dispersed metal clusters. Zeolite matrices combine the factors of nanoporosity and nanometer-scale chemical reactivity with respect to incorporated foreign ions, clusters, and nanoparticles [1]. 

Microporous inorganic materials dominated historically by the 2eohtes and alumosilicates, and the great variety of more recent nonoxide and coordination framework materials should also be mentioned here (171—174) but not discussed in detail. This type of molecular recognition is usually known as molecular sieving.
