Book excerpt: Given the rapid increase in atmospheric concentration of CO2, the development of efficient CO2 capture technologies is critical for the future of carbon-based energy. Currently, the most commonly employed approach to capture CO2 is amine scrubbing in which amine-based solvents react with gaseous CO2 to form carbamate. Although the amine-based solvents such as monoethanolamine (MEA) exhibit high CO2 capture capacity, their high volatility results in corrosive fumes and energy-intensive regeneration process. Therefore, there is an urgent need to develop alternative CO2 capture media that can be efficient and environmentally sustainable. To achieve this goal, a new class of CO2 capture media named Nanoparticle Organic Hybrid Materials (NOHMs) has been formulated. A unit of NOHMs consists of a surface-functionalized nanoparticle as a core to which selected polymers are tethered to form a canopy. Such a configuration prevents loss of polymers and enables NOHMs to exhibit near zero vapor pressure.
