Highly Selective Supported Graphene Oxide Membranes for Water-Ethanol Separation

Carbon membranes for efficient water-ethanol separation.

We demonstrate, on the basis of molecular dynamics simulations, the possibility of an efficient water-ethanol separation using nanoporous carbon membranes, namely, carbon nanotube membranes, nanoporous graphene sheets, and multilayer graphene membranes. While these carbon membranes are in general permeable to both pure liquids, they exhibit a counter-intuitive "self-semi-permeability" to water ...

Understanding water permeation in graphene oxide membranes.

Water transport through graphene-derived membranes has gained much interest recently due to its promising potential in filtration and separation applications. In this work, we explore water permeation in graphene oxide membranes using atomistic simulations and theoretical analysis, by considering flow through the interlayer gallery, expanded channels such as wrinkles of interedge spaces, and po...

Highly permeable supported γ-alumina membranes for water purification

Nanofiltration with inorganic meso-porous membranes is being considered more and more for water purification applications. For specific applications inorganic membranes may have advantages over organic polymer-based membranes due to their rigid pore structure, and thermochemical stability. However, the permeability and, partly through that, the permselectivity of inorganic membranes need to be ...
