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 CO 2 permeation performance (CO 2 permeability: 100 Barrer, CO 2 /N 2 selectivity: 91) and extraordinary operational stability (>6000 min), which are attractive for implementation of practical CO 2 capture.
