Research Abstract

Silica mesoporous crystals have well-ordered meso-structures with the pore size of several nanometers. We have investigated their structures by electron microscopy and developed three dimensional (3D) reconstruction methods such as electron tomography. The results were as follows ; (i) we characterized 3D networks of mesopores in spherical silica mesoporous materials, (ii) we observed new tetrahedrally close-packed structures in cage-type silica mesoporous materials.
