Recent advances in development of amine functionalized adsorbents for CO2 capture

As one of the most promising candidates for adsorptive removal of CO2, amine-based solid adsorbents have been widely investigated by many researchers around the world in the past few years. This class of materials offers great potential for replacing the current energy intensive amine scrubbing technology and address the scalability of adsorption-based capture processes. In this review, we discuss the recent advances in development and evaluation of various types of amine functionalized materials, aiming at providing a comprehensive overview of the current progress and the future directions with respect to both materials development and process application. While there have been recent broad reviews on CO2 capture processes and in particular adsorbent materials for CO2 capture, here we will narrow down our focus on only amine-based materials due to their significant promises in efficiently capture CO2 from various gaseous streams and examine the current state-of-the-art research on these fascinating class of materials.
