Abstract
Disclosed is a modified carbonaceous material, which includes hexagonal carbon networks in a layered stacking structure and acidic functional groups bonded to the hexagonal carbon networks and mainly existing at edges of the layered carbonaceous structure. Accordingly, the close proximity of acid moiety at the edges can resemble the center of hydrolysis enzymes, resulting in enhancement of hydrolytic efficiency. Additionally, the acid-functionalized carbonaceous material can also be applied in the capture and storage of carbon dioxide due to its unexpectedly higher capacity for CO2 molecular.
Claims9
A CO2-capturing acid-functionalized adsorbent, comprising hexagonal carbon networks in a layered stacking structure and acidic functional groups bonded to the hexagonal carbon networks, wherein the hexagonal carbon networks substantially consist of aromatic carbons, and substantially all of the acidic functional groups are covalently linked to in-plane sp2 carbons at edges of the hexagonal carbon networks.
