Facile tailoring of the two-dimensional graphene oxide channels for gas separation†
Abstract
This work demonstrates a facile method of finely tailoring the graphene oxide (GO) nanochannels by controlling their surface oxygenated functionalities. The as-prepared membrane with subnanometer interlayer nanochannels (0.36 nm) and CO2-philic properties showed excellent preferential CO2 permeation performance, which offers promising potential for CO2 capture.
