Advancing Molecular Sieving via Å-Scale Pore Tuning in Bottom-Up Graphene Synthesis

Kumar Varoon Agrawal, Mounir Driss Mensi, Kangning Zhao, Heng-Yu Chi, Cédric Karel J Van Goethem, Yueqing Shen

Porous graphene films are attractive as a gas separation membrane given that the selective layer can be just one atom thick, allowing high-flux separation. A favorable aspect of porous graphene is that the pore size, essentially gaps created by lattice def ...
