Graphyne-4 sheet exhibits promising potential for nanoscale desalination to achieve both high water permeability and salt rejection rate. Extensive molecular dynamics simulations on pore-size effects suggest that graphyne-4, with 4 acetylene bonds between two adjacent phenyl rings, has the best performance with 100% salt rejection and an unprecedented water permeability, to our knowledge, of ~13L/cm2/day/MPa, about 10 times higher than the state-of-the-art nanoporous graphene reported… 
Atomistic and continuum scale modeling of functionalized graphyne membranes for water desalination.
This upscale analysis shows that the significant increase in permeability, observed from MD simulations, does not fully translate to current RO systems due to transport limitations, but upscale calculations predict that the higher permeability of graphyne membranes would allow up to six times higher permeate recovery or up to 6% less energy consumption as compared to thin-film composite membranes at currently accessible operating conditions.
Molecular insights into water desalination performance of pristine graphdiyne nanosheet membrane.
The molecular simulations were done to investigate the salt rejection from aqueous solution through the pristine graphdiyne (graphyne-2) nanosheet and demonstrated that the graphdiyahne membrane has 100% salt rejection at pressures <400 MPa, and its permeability is higher than conventional polymeric membranes.
