Abstract

The structure of the amorphous walls of the mesoporous material MCM-48 was investigated with a combination of high-resolution transmission electron microscopy and selected area electron diffraction, and the three-dimensional structure was reconstructed by electron crystallography. The crystals were well ordered over large areas as shown by the images and diffraction patterns. It was firmly confirmed from Fourier transforms of thin areas that MCM-48 belongs to the Ia3d space group and that the amorphous walls roughly follow the gyroid surface (a minimal surface), but the wall thickness is not uniform.
