Ordered porous materials on the meso-structural scale have attracted great attention due to their ordered porous structure, large surface area and unique spatial confinement effect, which may find widespread applications in adsorption, separation, catalysis, sensing, drug delivery, energy storage, etc. The in-depth analysis of the structural characteristics of these porous materials is not only essential for understanding their properties and performances, but also the key for the future materials synthesis and their formation mechanism. The structural solution of porous materials on the meso-structural scale by using electron microscopy for last decades was outlined, which shows great advantages in the structural solution of the porous solids through diffractometry and imaging. Several representative examples including ordered mesoporous materials and macro-porous scaffolds, have been solved by appropriate methods. Then, the electron microscopy methods applicable to different types of porous materials were summarized. Finally, the advantages, limitations and future development of electron microscopy towards new porous materials, as well as the feasibility of using this technique for other materials were concluded.

Key words: mesoporous material, macro-porous material, electron microscopy, 3D reconstruction, crystal defect
