Abstract

See full text

A structure and method for carbon capture, e.g., in flue gas. An oxygen-terminated crown pore in graphene can be provided. Exposed carbon atoms on the pore edge can be bonded with oxygen to make a crown pore. When the CO2 is inside the pore, the electrostatic interaction becomes attractive because the positively charged carbon atom in CO2 is now exposed to negatively charged oxygen atoms on the crown pore edge. A favorable interaction between CO2 and the crown pore can be expected.
