| Abstract |
| With conventional water sources in short and decreasing availability, new technologies for water supply have an essential role to play in addressing the world's clean water needs in the 21st century. In this paper, we show how nanometer-scale pores can excellently filter NaCl salt from water. Using classical molecular dynamics, we show the relation between the desalination performance with the pore size and applied pressure. Our results suggest that the membranes allow the water to pass through pores with diameter in the 0.68-85 nm range while blocking NaCl ions to pass through pores and will push them back to the behind of the membranes. Further, our results indicate that the water permeability of this membrane is significantly higher than conventional reverse osmosis membranes, and that nanoporous graphene may have a valuable role to play for water purification. |
