CO capture by amine-functionalized nanoporous materials: A review.

Amine-functionalized nanoporous materials can be prepared by the incorporation of diverse organic amine moieties into the pore structures of a range of support materials, such as mesoporous silica and alumina, zeolite, carbon and metal organic frameworks (MOFs), either by direct functionalization or post-synthesis through physical impregnation or grafting. These hybrid materials have great potential for practical applications, such as dry adsorbents for post-combustion CO capture, owing to their high CO capture capacity, high capture selectivity towards CO compared to other gases, and excellent stability. This paper summarizes the preparation methods and CO capture performance based on the equilibrium CO uptake of a range of amine-functionalized nanoporous materials. [ABSTRACT FROM AUTHOR]
