Dr. Johan Groen of Delft Solids Solutions delivers an oral presentation during the NCCC conference in Noordwijkerhout in the Netherlands. The lecture concerns the application of desilication to constitute hierarchical zeolites of different chemcial composition.
The lecture evidences that the use of desilication is not restricted to aluminosilicate zeolites having silicon and aluminium in the framework, but can also be applied to zeolites containing other trivalent cations (Fe, B, en Ga). These cations regulate in a similar way the silicon extraction towards mesoporosity development. These results prove desilication to be a fairly universal methodology for post-synthesis modification of zeolites of different framework topology but also of different chemical composition. Desilication can be used to process a wide variety of zeolites into valuable hierarchical structures.
The lecture will be held on 3 March 2009, 09:55 h.
