Carbon sorbent-azobenzene hybrids for carbon capture and methods of producing and/or using said hybrids

Abstract

Modified carbon-based sorbents configured for improved carbon capture, methods for increasing COcapture potential of modified carbon-based sorbents, and methods for improving noncovalent interactions of modified carbon-based sorbents with CO, N, and Hare disclosed herein. The modified carbon-based sorbents have porous carbon surfaces and/or mesoporous carbon surfaces comprising one or more in-plane sites having at least one first nitrogen functionality and one or more out-of-plane sites having at least one second nitrogen functionality, wherein the at least one first nitrogen functionality is a different nitrogen functionality than the at least one second nitrogen functionality. The methods comprise contacting the modified carbon-based sorbents to gaseous streams containing CO.
