WebThe applicability of graphene-based materials, especially GO, in membranes for gas separation has been an active area of research, owing to its 2D morphology and monoatomic thickness, which theoretically gives the lowest possible transport resistance. ... Jin, W.; Xu, N. Subnanometer two-simensional graphene oxide channels for ultrafast … WebThe incorporation of angstrom-sized pores in single-layer graphene at moderate to high density is highly desirable to achieve an ultrahigh separation performance, attributing to the fact that graphene is the thinnest molecular barrier (1–6).Several molecular simulations and transport calculations have shown that a single-layer graphene, hosting a high density of …
