Heteroepitaxially-grown Zeolitic Imidazolate Framework Membranes with High-Resolution Propylene/Propane Separation Performance |
| 초록 |
We report the first well-intergrown membranes of ZIF-67 (Co-substituted ZIF-8) by heteroepitaxially growing ZIF-67 on ZIF-8 seed layers. The ZIF-67 membranes exhibited record-high propylene/propane separation factors of ∼200, which is better than all reported ZIF-8 (isostructural to ZIF-67) membranes. Spectroscopic evidences combined with computational study support our hypothesis that the high-resolution propylene/propane separation originates from intrinsically better kinetic selectivity of ZIF-67 for propylene/propane molecules than ZIF-8 due to smaller pore aperture. |
