Claim:
1. A membrane, comprising: a graphene layer perforated by a plurality of nanoscale pores; and a gas sorbent comprising a material perforated by a plurality of gas sorbent pores, wherein the material contacts a surface of the graphene layer such that at least one portion of the plurality of nanoscale pores and at least one portion of the plurality of gas sorbent pores are aligned and the at least one portion of the plurality of nanoscale pores is free from obstruction by the material, wherein the material adsorbs at least one gas and is permeable to the adsorbed at least one gas such that the gas sorbent is configured to direct the at least one gas into the plurality of nanoscale pores, and wherein a hydrogen and methane separation selectivity of the membrane is between about 200:1 and about 10^23:1.
