Crystallographic microscopy: Zeolite ZSM-5 is one of the most used solid acid catalysts in the oil refining and chemical industries. Synchrotron-based micro X-ray diffraction imaging has been used to spatially resolve the internal crystallographic 3D architecture of ZSM-5 intergrowths and to visualize the zoning of aluminium at the single-catalyst-particle level.
