Abstract
The polymeric gutter layers of current thin film composite membranes (TFCMs) suffer from high gas diffusion resistance and fast performance deterioration. We designed a TFC membrane consisting of an ultrathin 2-D MOF nanosheets gutter layer and an ultrathin selective microporous polymer top layer via interfacial polymerization for H2 separation. The 2-D MOF nanosheets gutter layer was shown to be thin and highly permeable with extremely low resistance for gas transport, thereby maximizing the gas permeance of the resulting composite membranes. The resulting TFCMs exhibited outstanding H2 permeance (8.2 × 10−7 mol m−2 s−1 Pa−1) with an ideal H2/CO2 selectivity of 12.3–12.6. In addition, the TFCMs showed excellent long-term stability due to the rigidity and integrity of the 2-D MOF nanosheets. This study is expected to provide a new approach to design high performance TFCMs for H2 separation.
