Implication

Experimental study demonstrates selective gas transport in layered graphene oxide membranes, indicating strong potential for postcombustion carbon dioxide capture.

Key Points

To engineer few- and several-layered graphene and graphene oxide membranes with tailored nanochannels for selective gas separation.
Fabricated layered graphene and graphene oxide (GO) membranes ranging from 3 to 10 nanometers in thickness.
Controlled gas flow channels and pores by varying the stacking methods and structural interlocking of the nanosheets.
Evaluated gas diffusion and selectivity under varying relative humidity conditions relevant to postcombustion gas streams.
Gas transport behavior was tunable and directly governed by the degree of interlocking within the 3- to 10-nanometer GO stacking architecture.
Well-interlocked GO membranes achieved high carbon dioxide over nitrogen selectivity under conditions of high relative humidity.
The engineered membranes proved suitable for postcombustion carbon dioxide capture operating with humidified feed streams.
