A recent experiment (Koenig et al., 2012 [15]) demonstrated the capability of porous graphene as one-atom-thin membrane to separate gases by molecular sieving. A quantitative connection between the measured leak rate and the simulated gas permeance has yet to be established. Using H 2 as a model gas, here we determine its permeance through porous graphene from molecular dynamics (MD) simulations...
