Amine-oxide hybrid materials for acid gas separations

Author affiliations

Abstract

Organic–inorganic hybrid materials based on porous silica materials functionalized with amine-containing organic species are emerging as an important class of materials for the adsorptive separation of acid gases from dilute gas streams. In particular, these materials are being extensively studied for the adsorption of CO2 from simulated flue gas streams, with an eye towards utilizing these materials as part of a post-combustion carbon capture process at large flue gas producing installations, such as coal-fired electricity-generating power plants. In this Application Article, the utilization of amine-modified organic–inorganic hybrid materials is discussed, focusing on important attributes of the materials, such as (i) CO2 adsorption capacities, (ii) adsorption and desorption kinetics, and (iii) material stability, that will determine if these materials may one day be useful adsorbents in practical CO2 capture applications. Specific research needs and limitations associated with the current body of work are identified.
