To enhance the carbon dioxide (CO2) uptake of metal-organic frameworks (MOFs), amine functionalization of their pore surfaces has been studied extensively. In general, amine-functionalized MOFs have been synthesized via post-synthetic modifications. Herein, we introduce a one-step construction of a MOF ([(NiLethylamine)(BPDC)] = MOFNH2; [NiLethylamine](2+) = [Ni(C12H32N8)](2+); BPDC(2-) = 4,4'-...

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...

Direct air capture (DAC) is becoming a technically feasible negative emission technology; however, the fabrication of affordable adsorbents with large CO 2 capacities, fast kinetics, and high sorption-desorption stability are critical importance for large-scale deployment DAC process. In this study, amine functionalized, aqueous miscible organic Mg x Al-CO 3 layered double hydroxide (LDH) nanos...

The new magnetic amine-functionalized graphene oxide (Fe3O4-GO-NH2) nanocatalyst was prepared through the reaction of 3-aminopropyltriethoxysilane (APTES) with magnetic graphene oxide (Fe3O4-GO). It was characterized by XRD, TEM, SEM, FT-IR and EDX techniques. The intrinsic carboxylic acids on the edges of Fe3O4-GO alo...

The covalent linkage of graphene acid (GA) with amine-functionalized UiO-66-NH 2 via an amide bond. resultant hybrid GA@UiO-66-NH acts as a chemiresistive CO sensor wth significant efficiency owing to its unique structural features.
