How does amine functionalization affect CO2 adsorption?4 answersAmine functionalization has been shown to enhance CO2 adsorption capacity and selectivity in various adsorbents. The introduction of amine groups into materials such as nanosilica, hypercrosslinked polymer (HCP), UiO-66-NH2 aerogel, solid resin base, and zeolite NaA and analcimeincreases their CO2 adsorption capabilities. The amine-functionalized materials exhibit higher CO2 adsorption capacities compared to their non-functionalized counterparts. The maximum CO2 adsorption capacity is significantly improved after amine functionalization, as observed in nanosilica, HCP, UiO-66-NH2 aerogel, solid resin base, and zeolite NaA and analcime. Additionally, amine functionalization enhances the selectivity of the adsorbents for CO2 over other gases such as N2 and CH4. The amine-functionalized materials also demonstrate good regeneration stability and recycling performance, making them promising candidates for CO2 adsorption applications.

PEI-impregnated FAU zeolite showed high CO2 adsorption capacity and rate under dry conditions, and an enhanced adsorption capacity under humid conditions. TEPA-incorporated γ-Al2O3 samples exhibited high CO2 adsorption capacities at ambient and cold temperatures, with further improvement when moisture was introduced. TEPA-modified hierarchical silica particles demonstrated high CO2 uptake and excellent amine efficiency under DAC conditions, as well as good performance under humid conditions.

Optimizing the durations of the adsorption and regeneration phases, as well as choosing appropriate operating parameters, can significantly improve DAC performance.
Adsorption capacity for Solid Amine-Based Materials?5 answersSolid amine-based materials have shown high adsorption capacities for CO2 capture. Various methods have been explored to enhance the adsorption performance of these materials. One approach is the impregnation of amine onto different supports such as silica, polymeric resin, and alumina-extracted residue of coal ash. The loading amount of amine, impregnation method, and adsorption temperature have been studied to optimize the adsorption capacity. For example, HMS-4 h-75%TEPA, a macro-/mesoporous multimodal pore silica impregnated with tetraethylenepentamine (TEPA), exhibited a high adsorption capacity of 6.04 mmol/g at 90 °C and 1 bar. ADS-17–40%TEPA, a TEPA-impregnated porous polymeric resin, achieved a CO2 adsorption capacity of 264.2 mg/g at a flow rate of 200 mL/min. Particle Molecular Layer Deposition (MLD) was used to functionalize supported amine sorbents, resulting in an adsorption capacity of ~0.005 mmol/m2. Wet gel impregnation of TEPA onto alumina-extracted residue of coal ash yielded a sorbent with a maximum CO2 adsorption capacity of 3.45 mmol/g at 75 °C. These studies demonstrate the potential of solid amine-based materials for efficient CO2 capture.
