Synthesis and Catalytic Consequences of Encapsulation of Metal Clusters and Acid Sites within Small Voids Via Interzeolite Transformations

We report synthetic protocols and guiding principles for the synthesis of zeolites without organic structure-directing agents via interzeolite transformations. These protocols can also be used to retain encapsulated metal clusters within zeolite frameworks, thus providing a strategy for encapsulation into structures for which more direct methods of encapsulation are unavailable.
