The effect of increasing atmospheric CO2 concentration on global climate change is recognized as one of the most important environmental issues facing society today. Although amine-based absorption is the current state-of-the-art technology for capturing CO2, it is not clear that absorption technologies alone will lead to the cost reductions required to achieve a gigaton-scale solution to CO2 emissions. For this reason, adsorption technologies have been a major focus of recent research and development.Adsorption-based technologies for CO2 capture have several advantages over the traditional amine-based solvent absorption approaches. For instance, within an adsorption-based approach water is absent, which decreases the energy requirements associated with regeneration since heating a large amount of water is the greatest energetic expense associated with CO2 capture using solvent-based approaches. Another benefit of using solid sorbents is the ability to tune the structural parameters of the material, as well as perform chemical modifications to enhance CO2 uptake.  In addition, materials such as carbon possess favorable heat conduction properties.This work mainly focuses on the facile synthesis of nitrogen-doped micro/mesoporous carbon sorbent with highly ordered, hierarchical porous structures with high surface area. This sorbent showed promising CO2 capacity compared to commercial activated carbon and possesses the potential of applications in dynamic column adsorption processes. Furthermore, the idea of surface functionalization of zinc mimicking carbonic anhydrase was tested by proof-of-concept experiments.
