Two-dimensional polyphenylene: experimentally available porous graphene as a hydrogen purification membrane.
We demonstrate computationally that two-dimensional polyphenylene is a typical semiconductor with a wide band gap, and the porous structure endows polyphenylene remarkably high selectivity for H(2) permeability relative to CO(2), CO and CH(4). This experimentally available porous graphene is expected to find applications in a hydrogen energy society.
