Abstract

We present here a series of experiments performed by electron tomography with the main goal to investigate the 3D porous characteristics that can be encountered in the course of preparing micro- and mesoporous materials. The examples are chosen in order to illustrate the ability of this technique to furnish direct information of various natures: morphological, concerning the accessibility to a internal surface of a porous sample, as well as on the shape and 3D ordering of the cavities in a porous network. All these parameters are of prime importance in the catalysis field, since they govern the catalytic performances of the sample. The results underline the uniqueness and the benefits of this technique to provide relevant information on different types of porosities on a nanometer scale
