Membranes for CO2 Separation

Metal-organic frameworks (MOFs) are crystalline nanoporous materials. We identify promising ultramicroporous (d < 0.7 nm) MOFs for CO2 separation and develop wet method for the fabrication of dense MOF membranes. We investigate the properties of MOF membranes for CO2 separation in flue gas or natural gas. We also explore new MOF membranes for hydrogen purification. We are particularly interested in transport mechanism of gases within MOF membranes.


We study MOF membranes for pervaporation, involving separation of ethanol/water as well as IPA water. We look for MOFs with high hydrophilicity for this application. We develop new method to prevent the ageing of MOF membranes when being in contact with water or alcohol.
