  The low efficiency of commercially-used reverse osmosis (RO) membranes has
been the main obstacle in seawater desalination application. Here, we report
the auspicious performance, through molecular dynamics simulations, of a
seawater desalination filter based on the recently-synthesized graphene-like
carbon nitride (g-C2N) [Nat. Commun., 2015, 6, 6486]. Taking advantage of the
inherent nanopores and excellent mechanical properties of g-C2N filter, highly
efficient seawater desalination can be achieved by modulating the nanopores
under tensile strain. The water permeability can be improved by two orders of
magnitude compared to RO membranes, which offers a promising approach to the
global water shortage solution.
