Encapsulation of metal nanoparticles

The aim of the project is to develop novel heterogeneous catalysts by encapsulation of metal nanoparticles in zeolites.

The encapsulation of metal nanoparticles in zeolites has recently attracted much attention because the zeolite framework may introduce selectivity in terms of size- and shape selectivity or prevent the encapsulated nanoparticles from sintering by Ostwald ripening or particle migration and coalescence. It has previously been argued that the encapsulation of metal nanoparticles in small and medium-pore zeolites may preclude post-synthetic methods, such as ion-exchange or impregnation, which require the migration of solvated metal-oxo oligomers that cannot diffuse through the small apertures in these materials. Much effort has therefore been devoted to develop bottom up approaches, where the metal nanoparticles are formed prior to zeolite crystallization or recrystallization. Although the encapsulation of preformed nanoparticles is an effective and elegant concept, they often rely on complex synthetic procedures and expensive additives, which may prevent large-scale production and general implementation. This project aims to develop more effective and scalable methods to encapsulate metal nanoparticles in zeolites.
