The introduction of nanoscale pores in graphene has attracted much attention for a large variety of applications that involve water purification, gas filtration, chemical separation, and DNA sequencing. Graphene has been proposed as an effective separation membrane. Removing carbon atoms to form size-controlled nanopores, size-selective separation membrane might be possible based on the molecular sieving effects.

In this Thesis project, we aim at studying formation mechanism and edge natures of sub-nanometer size nanopores in graphene for gas filtration membrane application. The final objective is to realize size-controlled stable nanopores in graphene monolayers using plasma technology and to integrate the developed nanopore formation process into gas filtration membrane technology to test their selectivity especially on hydrogen separation.
