Facile tailoring of the two-dimensional graphene oxide channels for gas separation

摘要

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 CO _(2) -philic properties showed excellent preferential CO _(2) permeation performance, which offers promising potential for CO _(2) capture.
