TL;DR: In this 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) adorption and desorption kinetics, and (iii) material stability, that will determine if these materials may be useful adsorbents in practical CO2 capture applications.

TL;DR: It is suggested that the important role of the surface properties of the oxide support in these polymer/oxide composite adsorbents has been largely overlooked and that the properties may be even further enhanced in the future by tuning the acid/base properties ofthe support.

TL;DR: In this article, it is known that the MEA oxidative degradation rate is a critical parameter affecting liquid amine amine (LAM) degradation in coal-fired power plant flue gas exhaust.

TL;DR: The CO(2) capacity and organic content of all adsorbents decrease after steam treatment under both steam/air and steam/nitrogen conditions, primarily due to structural collapse of the MCF framework, but with additional contributions likely associated with amine degradation during treatment under harsh conditions.

TL;DR: Primary amines are confirmed to be the most effective amine types for CO2 capture from ambient air, but this is not due to enhanced enthalpic contributions associated with primary amines over secondary amines, but may be due to unfavorable entropic factors associated with organization of the second alkyl chain on the secondary amine during CO2 adsorption.
