Electrochemical-repaired porous graphene membranes for precise ion-ion separation

Kumar Varoon Agrawal, Kangning Zhao, Heng-Yu Chi, Kuang-Jung Hsu, Mojtaba Chevalier, Yueqing Shen, Shuqing Song, Zongyao Zhou

The preparation of atom-thick porous lattice hosting & Aring;-scale pores is attractive to achieve a large ion-ion selectivity in combination with a large ion flux. Graphene film is an ideal selective layer for this if high-precision pores can be incorpora ...

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 ...

Bottom-up synthesis of graphene films hosting atom-thick molecular-sieving apertures

Emad Oveisi, Kumar Varoon Agrawal, Kangning Zhao, Victor Carle Adrien Boureau, Luis Francisco Villalobos Vazquez de la Parra, Shiqi Huang, Mostapha Dakhchoune, Shaoxian Li, Kuang-Jung Hsu, Cédric Karel J Van Goethem, Yueqing Shen, Mina Moradi

Incorporation of a high density of molecular-sieving nanopores in the graphene lattice by the bottom-up synthesis is highly attractive for high-performance membranes. Herein, we achieve this by a controlled synthesis of nanocrystalline graphene where incom ...
