Schnell und selektiv ist der Gastransport in Membrankanälen, die von schichtförmig angeordneten Graphenoxidblättern gebildet werden. Darüber berichten W. Jin et al. in der Zuschrift auf S. 588 ff. Mit Zwischenräumen, die als Molekülsiebe wirken, und direkten Diffusionspfaden verleihen die Graphenoxidlaminate Gastrennmembranen eine selektive CO2‐Durchlässigkeit und Betriebsfestigkeit, die vielversprechend...
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...
