2d Materials based graphene for Water desalination applications

2D Materials based graphene has an excellent potential to be used as a RO membrane due to its unique properties such as mechanical and chemical stability,^1,2 However improving water permeability with an excellent salt rejection rate remains a significant challenge. We propose a novel water filtration membrane based on two-electrode nano-porous graphene on substrate. We used two types of substrate SiO₂ and SiC. Nano-pores were created by argon-plasma magnetron sputtering then quantified using Raman spectroscopy. Using Molecular Dynamics Simulations, our proposed concept makes it possible to have the highest permeability value, keeping almost 100 % salt rejection and improving its mechanical properties. These reported results are essential for developing water desalination membranes based on graphene devices
