Large-Pore Mesoporous Materials with Semi-Crystalline Zeolitic Frameworks

Abstract

Crystallizing walls: Following the templated solid-state secondary crystallization of an amorphous mesoporous material the amorphous pore walls of the mesoporous precursor are partially reorganized into a crystalline material, the zeolite ZSM-5, as indicated by the dark-field transmission electron micrograph image shown. The bright spots correspond to the ZSM-5 nanocrystals.
