Abstract
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 COis inside the pore, the electrostatic interaction becomes attractive because the positively charged carbon atom in COis now exposed to negatively charged oxygen atoms on the crown pore edge. A favorable interaction between COand the crown pore can be expected.
