Abstract
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.
