摘要: Forward osmosis (FO) technology has shown great promise in sea water desalinization and power generation from the mixing of fresh seawater estuaries. However, desalination efficiency density level present FO systems are very low owing to flux commercial membranes. In this study, we report brine separation performance single-layer graphyne-N (N = 3, 4, 5, 6) membranes a forward system by molecular dynamics simulation. Our calculations show that graphyne-3 not only can achieve high up about 39.15 L cm−2 h−1, which is three four orders magnitude higher than conventional osmotic membranes, but also perfect salt rejection rate. The results indicate structural characteristics charge properties these as well distribution pattern both molecules ions each system, main factors affect graphyne Besides, found formation hydrated basic reason for solutions. Graphyne have good prospects separation, regeneration-free applications salinity FO.
