Abstract

See full text

Compositions, devices, and methods relating to the use of mixed-matrix membranes containing metal-organic frameworks to separate gases are generally described. In some embodiments, branched nanoparticles made at least in part of metal-organic frameworks are described. In some embodiments, the morphology and size of the branched nanoparticles are controlled by the presence of a chemical modulator during synthesis. In some embodiments, the branched nanoparticles are uniformly distributed in a mixed-matrix membrane. In some embodiments, the mixed-matrix membrane is configured to separate one or more gases from a gas mixture. In some embodiments, the branched nanoparticles contribute at least in part to an increase in permeability, selectivity, and/or resistance to plasticization of the mixed-matrix membrane.
