Raman studies of the templated synthesis of zeolites

Primary tabs

Knops-Gerrits, PPHJM Cuypers, MGLJ

The application of confocal Raman and FT-Raman in the understanding of zeolite synthesis is a goal that can be reached by studying different levels of complexity. First, the Raman properties of TEOS and its polymerization products under acid conditions is investigated. Structural characterization of zeolite framework vibrations is related to their building blocks such as prisms and sodalite cages. The Raman study of zeolite synthesis with structure directing agents permits the study of the geometry of these organic molecules, such as in ZSM-5 synthesis, the tetra-propyl-ammonium ion (TPA(+)), in EMT synthesis the Na-18-Crown-6 that can direct hypo- (and hyper-)cage formation, Can Li and co-workers performed zeolite X synthesis studies and FAU (X,Y), MFI, MOR and BETA characterization with UV-Raman.
