摘要：

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: 100Barrer, CO2/N-2 selectivity: 91) and extraordinary operational stability (>6000min), which are attractive for implementation of practical CO2 capture.
