A method to separate a gas from a f luid mixture, comprising: providing a f lu id mixture that includes a first g as and a second gas, wherein a molecule of the second gas is larger than a molecule of the first gas; providing a graphene layer perforated by a plurality of nanoscale p o res, wherein each of the pl urality of nan oscale pores has a diameter t h at selecti vely fa cilitate s passage of the first gas compared to the second gas; 4 S/N: 1 4/703,730 providing a gas sorbent that comprises a material perforated by aphuralit y of gas sorbent pores wherein the material contacts a surface of the gphenelayersuch that ateast oneprtion of the plurality of nanoscale pores and at least one portion of the plurality of gas sorbent pores are aliuned and the at least one portion of the plurality of nanoscale pores is free from obstruction by the material increasing a concentration of the first gas at [[a]] the. surface of the g rap he ne layer by contactin g the fluid mixture to [[a]] the gas sorbent at the grap hene layer, the gas sorbent comprising a material that contacts the surface of the graphene layer, wherein the m aterial adsorbs the f i rst gas an d is per m eable to the first gas such that the gas sorbent is configured to direct the first gas into the plurality of nanoscale pores; and selectively separating the first gas from the second gas according to size by employin g the pl u rali ty of nanoscale pores perforated in the graphene layer, wherein a hydrogen and methane separation selectivity is b etween about 200:1 and about 10' 23: 1.
Th e method of claim 18, wherein increasing the concentration of the fi r st gas at the s u rface of the gra ph ene layer inc lu des increasing a concentration of the first gas within about 1 micron of the g rap hene lay er. s
(O rig inal) The method of clai m 18, wherein selectively separating the first gas from the second gas inchi des directing the first gas through the pl u rality of n an oscale pores by applying a pr ocessi ng gradient across the gr aphene lay er, w he r e i n t he processing gradient corresponds to one or m ore o f a temperatu re gradie nt, a pressure gradien t, a gas co nc entration gradient, or an electric field g rad ient.
