This is a comparative study on the high-pressure behavior of microporous materials with an MFI framework type (i.e. natural mutinaite, ZSM-5 and the all-silica phase silicalite-1), based on in-situ experiments in which penetrating and nonpenetrating pressure-transmitting media were used. Different P-induced phenomena and deformation mechanisms (e.g. Pinduced over-hydration, P-induced amorphization) are discussed. The influence of framework and extra-framework composition and of the presence of silanol defects on the response to the high pressure of MFI-type zeolites is discussed.

Abstract
This is a comparative study on the high-pressure behavior of microporous materials with an MFI framework type (i.e. natural mutinaite, ZSM-5 and the all-silica phase silicalite-1), based on in-situ experiments in which penetrating and nonpenetrating pressure-transmitting media were used. Different P-induced phenomena and deformation mechanisms (e.g. Pinduced over-hydration, P-induced amorphization) are discussed. The influence of framework and extra-framework composition and of the presence of silanol defects on the response to the high pressure of MFI-type zeolites is discussed.File in questo prodotto:
