Abstract:
Disclosed are zeolitic imidazolate framework (ZIF) compositions in which at least a portion of the ligands in its shell have been exchanged with other ligands, and methods of making such shell-ligand-exchanged ZIFs. Also disclosed is the use of such shell-ligand-exchanged ZIFs in hydrocarbon separation processes.
