Hierarchical porous amorphous metal–organic frameworks constructed from ZnO/MOF glass composites.

For the first time, hierarchical porous amorphous metal–organic frameworks (HP-aMOFs) containing ultramicropores, micropores, and mesopores were synthesized by etching a composite of MOF glass (agZIF-76) and ZnO using ammonia. These materials show potential applications in the adsorption of C2 hydrocarbons. [ABSTRACT FROM AUTHOR]
