synthesis of nano particles of lta zeolite by means of microemulsion technique

this mini review article, intends to provide the essential information about microemulsion technique as a reliable approach toward the synthesis of zeolitic nano crystallites. the strategy discussed here provides a unique, effective, and potentially general methodology to the preparation of uniform and high purity nano crystallites of template-free zeolitic materials including lta, faujasite type and other zeolitic-like materials (i.e. zeotype materials). microemulsion is a reliable approach for controlled synthesis of uniform nano sized zeolitic particulates. on the other hand, the microwave assisted microemulsion technique has the advantages of short reaction time, producing smaller and more uniform particles with a narrower size distribution and high purity, in comparing to the conventional heating approaches.
