Improving CO2 adsorption with new amine-functionalized Y-type zeolite
In this work, a new synthesized Y-type zeolite with an Si/Al molar ratio of 2.5 (NaY) was modified with amines, in order to probe the influence of the modification of the adsorbent’s surface on CO2 adsorption. The three selected amines were diethanolamine, tetraethylenepentamine, and 2- methylaminoethanol. The surface nature of NaY was changed after amine modification, which causes a...
متن کاملProgramming MIL-101Cr for selective and enhanced CO2 adsorption at low pressure by postsynthetic amine functionalization.
MIL-101Cr fully or partially (p) postsynthetically modified with nitro (-NO2) or amino (-NH2) groups was shown to be a robust, water stable, selective and enhanced carbon dioxide (CO2) adsorption material with the amine-functionality. The highly microporous amine-modified frameworks (up to 1.6 cm(3) g(-1) total pore volume) exhibit excellent thermal stability (>300 °C) with BET surface areas up...
متن کاملDesign of amine-functionalized metal-organic frameworks for CO2 separation: the more amine, the better?
A total of 41,825 metal-organic frameworks (MOFs) were computationally screened toward the design of amine-functionalized MOFs for CO2 separation. Both the optimal species and number of amine functional groups were examined for eight MOFs with good performance in terms of CO2 uptake and selectivity. It was revealed that more amine functional groups grafted on the MOFs do not lead to a better CO...
متن کاملEfficient Removal of Co2+ from Aqueous Solution by 3-Aminopropyltriethoxysilane Functionalized Montmorillonite with Enhanced Adsorption Capacity
To achieve a satisfactory removal efficiency of heavy metal ions from wastewater, silane-functionalized montmorillonite with abundant ligand-binding sites (-NH2) was synthesized as an efficient adsorbent. Ca-montmorillonite (Ca-Mt) was functionalized with 3-aminopropyl triethoxysilane (APTES) to obtain the APTES-Mt products (APTES1.0CEC-Mt, APTES2.0CEC-Mt, APTES3.0CEC-Mt, APTES4.0CEC-Mt) with e...
متن کاملAn amine-functionalized MIL-53 metal-organic framework with large separation power for CO2 and CH4.
Functionalizing the well-known MIL-53(Al) metal-organic framework with amino groups increases its selectivity in CO(2)/CH(4) separations by orders of magnitude while maintaining a very high capacity for CO(2) capture.
