Nanoporous Graphene

Molecular dynamic simulation was used to investigate the ability of nanoporous graphene membrane in gas separation process. Three di-atomic gases (I2, N2 and O2) were considered, in which different pore sizes were modeled on graphene. The structure contains an impermeable movable wall (piston) to push the mixture gases toward the nanoporous graphene membrane. Two different simulations were carried out, with two different piston velocities. Two key factors in gases separation process are the pore size of graphene and the velocity of movable wall. The results revealed that I-129 separation was improved by using proper size of pore and by decreasing the velocity of movable wall. It was also found that the I-129 gas radionuclides could be completely separated from nitrogen and oxygen molecules in the pore-12 graphene configuration. It was also found that nitrogen was more strongly adsorbed onto the membrane than oxygen, while I-129 was not adsorbed.

And Control

A single graphene layer is superior many ways preferably in electronic devices application. However, mild modification of the graphene network could open a new potential to the ultrathin graphene membrane. Moreover, recent studies demonstrated that a few simple techniques could generate and control the nanopores size on single layer graphene sheet simultaneously. This review paper will discuss all potential techniques that are capable to generate nanopores structure on the pristine single layer graphene network.
