Beschreibungen/Notizen
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.
Between the sheets: Assembled graphene oxide laminates featuring molecular‐sieving interlayer spaces and straight diffusion pathways afford fast and selective channels for gas transport through the membrane. The membrane shows excellent preferential CO2 permeation from gas mixtures.
