The structural analysis of silica mesoporous crystals (SMCs) is a key step for understanding their properties, especially toward drug delivery. Although various techniques can be applied, electron crystallography has been proved the most powerful method in the structure solution of mesoporous materials. In this chapter, we will begin with introducing basic crystallography and extend to the 3D structure solution using a set of HRTEM images. Typical examples will also be given to show the structure features of 2D, 3D, cage-type, and hyperbolic surface-type mesostructures. A drug delivery system using SMCs as a reservoir will be given at the end.
