Transmission Electron Microscopy (TEM) is one of the most effective analytical tools for the study of zeolites. The performance of electron microscopes has advanced remarkably in recent years. Direct observations of mesopores in mesoporous silica and the surface steps of zeolite crystals are possible by Scanning Electron Microscopy (SEM). It has also become possible to observe the microstructures of materials on the atomic scale by standard High Resolution Transmission Electron Microscopy (HRTEM). Though such techniques are not straightforward., structural analysis of zeolites using TEM is becoming more widespread year by year. TEM is utilized for not only the analysis of zeolite microcrystals but also the study of applied zeolite materials. Here we describe in detail techniques for structure analysis of zeolites and mesoporous materials by TEM, and present results from their application to practical zeolite materials as examples.
