Mesoporous Metal-Organic Frameworks with Size-, Shape-, and Space-Distribution-Controlled Pore Structure

Mesoporous Metal–organic frameworks (meso‐MOFs) with size‐, shape‐, and space‐distribution‐controlled mesopores are obtained by a facile encapsulation and selective etching strategy of metal nanoparticles. Hierarchical or functionalized meso‐MOFs are achieved by the above strategy. Interestingly, the functional meso‐MOFs display higher catalytic activity originating from the mesopores existing in the MOFs, as well as good selectivity due to protection of the micro­porous frameworks.
