- Abstract
- Porous nanosheets made of effectively aligned zeolitic imidazolate framework-8 (ZIF-8), dubbed ZPGO, with an exceptionally high surface area (2170 m(2) g(-1)) were demonstrated. This composite was prepared by growing ZIF-8s on highly porous graphene oxide (PGO) and the mixed matrix membrane with such a nanofiller showed drastically improved size-selective CO2 transport even at very low filler concentration (0.02 wt%) especially under mixed gas conditions where both selectivity (CO2/N-2 similar to 57) and CO2 permeability (similar to 163 barrer) were significantly enhanced. In addition to this, ZPGO effectively suppressed CO2-plasticization, which indicates great potential in real operations. This new concept of nanofillers is expected to maximize the filler effect in other fields benefitting from a high surface area as well.
