Fibrous Metal–Organic Framework Membranes with Hierarchical Porous Channels for Efficient Carbon Dioxide Capture

The structural diversity and facile functionalization of metal–organic frameworks (MOFs) render them promising candidates for carbon dioxide (CO2) adsorption and separation. However, the powdery characteristics cause poor mechanical stability and insufficient gas mass transfer, restricting their further applications. Herein, we report a promising strategy of in situ assembling ZIF-8 on the inner and outer surfaces of nanofibers to develop the fibrous ZIF-8 membranes with hierarchical porous channels. Particularly, the developed meso/macropores of the fibrous ZIF-8 membranes could facilitate the transport of CO2 into ZIF-8, and the micropores of ZIF-8 offered massive active CO2 adsorption sites. As a benefit…
