Amine functionalized solid adsorbents are promising materials for the capture of CO2 because of their tunability and lower heat capacity compared to liquid amine solutions. This review focuses on recent advances in the use of solid-supported amines for CO2 capture, with emphasis on amine functionalized metal organic framework (MOF) materials. The recently reported diamine functionalized Mg-DOBPDC MOF demonstrates intriguing performance for CO2 capture, offering a unique adsorption mechanism with favorable energetics. Stable performance for CO2 capture under humid conditions and easy regenerability of the adsorbent are critical to the realization of practical CO2 adsorbents. Scalable regeneration methods such as temperature swing in a CO2 purge stream and temperature swing via steam stripping are discussed. Emerging gas-solid contacting strategies for CO2 capture with amine adsorbents are also discussed.
