Transmission electron microscopy in formation and growth of ordered mesoporous materials

In the boundary of materials and colloidal science, TEM became a very powerful technique used to image the interfaces and early stages of mesoporous materials formation, to obtain symmetry information about the porous network at the meso-scale, furthermore to obtain images of final structures and transformations that could not be observed otherwise. The aim of the present contribution is to give insights that may contribute to a better understanding of TEM applied to the study of ordered mesoporous materials from three points of view: i) mechanism ii) formation from zeolite precursors; iii) structure of intermediate mesophases.
