Sputtering yield for Na and Cl ions on a graphene and SiC membrane in the reverse osmosis method

Abstract

Graphene is a single layer thick consisted by honeycomb‐packed sp2 carbon atom; nanoporous graphene holds great promise in the application of filtration such as reverse osmosis method using a semipermeable membrane to remove ions, molecules, and larger particles from drinking water. The movement of molecules and ions can caused by a collision between the ions, molecules, and the graphene, so we can talk about the sputtering. In this work, we have studied the sputtering yield by Na and Cl ions to examine the potential and the challenges of osmosis membrane from graphene in order to predict the performance of the graphene membrane for use in the reverse osmosis method.
