The recent development of membrane-based water desalination and purification technologies shows new approaches to meeting global demand for freshwater. Carbon-based nanomaterials have shown great potential in various desalination technologies. Such materials are suitable for membrane separation, offering advantageous structure, mechanical properties and porosity. In the present molecular dynamics study, water desalination via reverse osmosis is simulated using a new sp(2)-carbon membrane. It is found that the membrane under consideration demonstrates a very good rate of ion rejection and a reasonably good water flux, which grows with increasing temperature.
