Synthesis and CO2 Capture Behavior of Porous Cross-Linked Polymers Containing Pendant Triazole Groups

“…5−7 However, it suffers from some inherent drawbacks, including degradation/loss, volatilization, corrosion, and high energy consumption. Therefore, a variety of promising solid adsorbents have been proposed for CO 2 capture in recent years, such as metal-oxides, 8 carbonates, 9 zeolites, 10,11 activated carbonaceous materials, 12 microporous/mesoporous silica, 13 amine-modified materials, 14−17 covalent organic frameworks (COFs), 18,19 and metal−organic frameworks (MOFs). 20−22 Among these sorbents, amine-modified porous materials, especially porous polymers, are recognized to be advantageous for CO 2 capture because of their high porosity, multifunctional active groups, simple preparation process, and low cost.…”

“…Curtailing CO 2 emission through energy consumption reduction as well as carbon capture, utilization, and storage (CCUS) is necessary to mitigate the global issue. − Currently, the most important industrialized CO 2 capture technology is chemical absorption using aqueous organic amines like monoethanolamine (MEA) as absorbent to removal of CO 2 from flue gas. − However, it suffers from some inherent drawbacks, including degradation/loss, volatilization, corrosion, and high energy consumption. Therefore, a variety of promising solid adsorbents have been proposed for CO 2 capture in recent years, such as metal-oxides, carbonates, zeolites, , activated carbonaceous materials, microporous/mesoporous silica, amine-modified materials, − covalent organic frameworks (COFs), , and metal–organic frameworks (MOFs). − Among these sorbents, amine-modified porous materials, especially porous polymers, are recognized to be advantageous for CO 2 capture because of their high porosity, multifunctional active groups, simple preparation process, and low cost . Amine is usually incorporated by two approaches: impregnation and surface grafting .…”

Flow MAS NMR for In Situ Monitoring of Carbon Dioxide Capture and Hydrogenation Using Nanoporous Solids

“…Amine-functionalized solid adsorbents, on the other hand, can be regenerated at low temperature (<373 K) and have high CO 2 adsorption capacities at low CO 2 partial pressure . In this regard, amine-functionalized porous silica materials, such as MCM-41 and SBA-15, were extensively studied for their CO 2 capturing performance. − …”
