| description | © 2017, Central South University Press and Springer-Verlag GmbH Germany. A zeolitic imidazolate hybrid membrane (Co-IM-mIM) containing two imidazolate ligands deposited on a macroporous a-alumina support was prepared by pre-depositing and secondary growth technique. XRD, TGA and SEM characterizations demonstrate that a stable and thin, but dense and pure-phase Co-IM-mIM membrane can be obtained on the macroporous-alumina discs in Teflon-lined autoclave at 120 °C after pre-depositing by dip-coating at room temperature. No visible cracks, pinholes or othe r defects were observed on the membrane layer. The gas separation studies of Co-IM-mIM membrane were carried out at 25 °C and 1×10 5 Pa, showing ideal selectivity of 6.95, 5.25, 3.40 for H 2 /CO 2 , H 2 /N 2 and H 2 /CH 4 , respectively, and a permeance of 17.37× 10 -6 mol/(m 2 ·s·Pa) for H 2 . The influence of temperature and trans-membrane pressure on hydrogen separation and permeation was also carried out. The gas permeation and selectivity demonstrate that this membrane may have potential applications for efficient H 2 separation. |
