Encapsulation of metal nanostructures into metal-organic frameworks.

Metal-organic frameworks (MOFs) have been demonstrated to be excellent hosts for metal nanostructures. Herein, a perspective of recent development achieved to control the location, composition, shape, and structure of the encapsulated metal nanostructures is provided. The interesting properties and potential applications of the designed metal@MOF composites as well as future challenges and opportunities in this field are also discussed.
