Review on CO2 Capture Using Amine-Functionalized Materials

High Resolution Image Download MS PowerPoint Slide CO 2 capture from industry sectors or directly from the atmosphere is drawing much attention on a global scale because of the drastic changes in the climate and ecosystem which pose a potential threat to human health and life on Earth. In the past decades, CO 2 capture technology relied on classical liquid amine scrubbing. Due to its high energy consumption and corrosive property, CO 2 capture using solid materials has recently come under the spotlight. A variety of porous solid materials were reported such as zeolites and metal–organic frameworks. However, amine-functionalized porous materials outperform all others in terms of CO 2 adsorption capacity and regeneration efficiency. This review provides a brief overview of CO 2 capture by various amines and mechanistic aspects for newcomers entering into this field. This review also covers a state-of-the-art regeneration method, visible/UV light-triggered CO 2 desorption at room temperature. In the last section, the current issues and future perspectives are summarized.
