Zeolites are an important class of technological materials.This kind of materials are open-framework Aluminosilicates built up by a Silica network around certain template molecules that are later removed to leave behind molecular-sized pores.In this paper the synthesis formulations and features of different zeolitetype structures prepared in nanosized form are summarized.Special attention is paid to zeolites prepared as stable colloidal suspensions.The methods for deposition of zeolite nanocrystals from suspensions onto supports of different shapes and composition used for the fabrication of zeolite films and membranes are studied.Applications of nanozeolites are in sensing, optoelectronics and used as catalysts adsorbents and ionexchangers. zeolites are characterizied by XRD and TEM techniques.
