Abstract
Biphenylene carbon is a porous carbon allotrope with a thickness of a single atom. An open question is wheter the BPC natural porosity can be exploited to create selective permeable membranes. We have carried out full atomistic Molecular Dynamics simulations to show that BPC is highly selective for H2. We have also investigated its possible application for H2 purification.

An open question is whether the biphenylene carbon (BPC) natural porosity can be exploited to create selective permeable membranes, which could lead to promising technological applications, such as gas separation
Our results show that BPC can exhibit selective permeability depending on the external pressure values
Summary
The recent discovery of new nanomaterials has already resulted in effective new applications. Graphene[1], a “two-dimensional” carbon structure with a single atom thickness, has been exploited in numerous technological applications, including selective membranes. It was recently demonstrated that graphene is impermeable to standard gases[2].
