Engineering of mesostructured silicas by pseudomorphism†
Abstract
Pseudomorphic transformation is introduced as an effective and versatile method to independently optimize the morphology of the grains and the structural properties of mesostructured silicas. In this account a short overview is given of the preparation of MCM-41 and MCM-48 mesophases as non-aggregated and homogeneously distributed particles with sizes ranging from 5 to 800 µm.
