Encapsulation of metal layers within metal-organic frameworks as hybrid thin films for selective catalysis

A facile encapsulation strategy for the preparation of metal layer/metal-organic framework （metal/MOF） hybrid thin films, by alternately growing MOF thin films and sputter-coating metal layers, is reported. The controlled species of the MOF thin films and metal layers, as well as the designed thickn...

Description
Summary:A facile encapsulation strategy for the preparation of metal layer/metal-organic framework （metal/MOF） hybrid thin films, by alternately growing MOF thin films and sputter-coating metal layers, is reported. The controlled species of the MOF thin films and metal layers, as well as the designed thickness of MOF thin films, endow the resulting hybrid thin films with improved functional and design flexibility. Importantly, the metaL/MOF hybrid thin films, with well-defined sandwich structures, exhibit excellent selective catalytic activity, derived from MOFs acting as molecular sieves and the metal layers providing active sites.
