Metal-Organic Frameworks Grown on Porous Planar Template with Exceptionally High Surface Area: Promising Nanofiller Platforms for CO2 Separation

Abstract

Porous nanosheets made of effectively aligned zeolitic imidazolate framework-8 (ZIF-8), dubbed as ZPGO, with exceptionally high surface area (2170 m2/g) was demonstrated. This composite was prepared by growing ZIF-8s on highly porous graphene oxide (PGO) and the mixed matrix membrane with such nanofiller showed drastically improved size-selective CO2 transport even at very low filler concentration (0.02 wt.%) especially under mixed gas condition where both selectivity (CO2/N2 ~57) and CO2 permeability (~163 Barrer) were significantly enhanced. In addition to this, ZPGO effectively suppressed CO2-plasticization, which shows great potential in real operations. This new concept of nanofiller is expected to maximize the filler effect in other fields benefitting from high surface area as well.
