Abstract

Graphene oxide (GO) nanosheets were engineered to be assembled into laminar structures having fast and selective transport channels for gas separation. With molecular-sieving interlayer spaces and straight diffusion pathways, the GO laminates endowed as-prepared membranes with excellent preferential CO₂ permeation performance (CO₂ permeability: 100 Barrer, CO₂/N₂ selectivity: 91) and extraordinary operational stability (> 6000 min), which are attractive for implementation of practical CO₂ capture.
