“…Thus, we want to study MOF which has abundant bases and micropores. Moreover, in recent years, it has been shown that the establishment for the porous MOFs with bifunctional ligands is a feasible way to obtain the donor positions discordant MOFs [20][21][22]. In this research, a novel MOF containing Co(II) ions as nodes f[Co(L)]Á4H 2 OÁ2CH 3 CNg n (1) have been prepared via Co(NO 3 ) 2 Á6H 2 O reacting with the bifunctional ligand 5-(3,5-di-pyridin-4-yl- [1,2,4]triazol-1-ylmethyl)-isophthalic acid (H 2 L) under the solvothermal conditions (Scheme 1).…”

A new metal-organic framework (MOF) formulated as f[Co(L)]Á4H 2 OÁ2CH 3 CNg n (1) has been prepared by solvothermal reaction of Co(NO 3) 2 Á6H 2 O with a bifunctional ligand 5-(3,5-di-pyridin-4-yl-[1, 2, 4]triazol-1-ylmethyl)-isophthalic acid (H 2 L) in a mixed solvent of DMA/H 2 O/CH 3 CN (DMA ¼ N,N-dimethylacetamide). The microporous MOF 1 has accessible alkaline sites which could be applied for the separation of C 2 H 2 from a gas mixture of C 2 H 2 / CO 2. The adsorption capacity of C 2 H 2 and selectivity of C 2 H 2 /CO 2 are equal to those of reference materials, which make the material hopeful to become a significant C 2 H 2 /CO 2 separation material. In biological functional study, the treatment activity of the compound on chronic obstructive pulmonary disease (COPD) was induced by influenza A virus infection. First, the relative expression of the tlr3 gene on the alveolar macrophages was measured with real time reverse transcription polymerase chain reaction (RT-PCR). The Enzyme Linked Immune Sorbent Assay (ELISA) detection was used for the evaluation of the inflammatory cytokines releasing after compound treatment against COPD. Finally, molecular docking was performed to predict the potential binding modes of the complex to TLR3 protein.

“…S5). The CO 2 /N 2 (15/85) separation selectivity on ZU-16-Co is up to 690 at 1.0 bar, much higher than that on r1KCHA (80) [18], NKU-521 (40) [39], UTSA-16 (314) [40], Mg-MOF-74 (150) [40], SIFSIX-2-Cu-i (140) [37] and UTSA-120a (600) [41]. Furthermore, CO 2 /CH 4 (50/50) separation selectivity on ZU-16-Co was calculated to be 120, also comparable to the state-of-the-art materials, such as SIFSIX-2-Cu-i (33) [37], SIFSIX-3-Zn (231) [37], 13X (103) [37], Mg-MOF-74 (137) [37], and MOF-505 (27.8) [42].…”

High and selective capture of low-concentration CO2 with an anion-functionalized ultramicroporous metal-organic framework

CO 2 capture, especially under low-pressure range, is of significance to maintain long-duration human operation in confined spaces and decrease the CO 2 corrosion and freezing effect for the liquefaction of natural gas. Herein, we for the first time report a novel anion-functionalized ZU-16-Co (TIFSIX-3-Co, TIFSIX=hexafluorotitanate (TiF 6 2−), 3=pyrazine), which exhibits one-dimensional pore channels decorated by abundant F atoms, for efficient CO 2 capture at a concentration around 400-10,000 ppm. Among its isostructural MFSIX-3 (M=Si, Ti, Ge) family materials, ZU-16-Co with fine-tuned pore size of 3.62 Å exhibits the highest CO 2 uptake at 0.01 bar (10,000 ppm) and 1 bar (2.63 and 2.87 mmol g −1 , respectively). The high CO 2 capture ability of ZU-16-Co originates from the fine-tuned pore dimensions with strong F•••C=O host-guest interactions and relatively large pore volumes coming from its longer coordinated Ti-F-Co distance (3.9 Å) in c direction. The excellent carbon trapping performance was further verified by dynamic breakthrough tests for CO 2 /N 2 (1/99 and 15/85) and CO 2 /CH 4 (50/ 50) mixtures. The adsorption and separation performances, resulting from the fine-tuned pore system with periodic arrays of exposed functionalities, demonstrate that ultramicroporous ZU-16-Co can be a promising adsorbent for low-concentration carbon capture.

“…This can be attributed to their ease of functionalization using CO 2 -philic functional groups. MIL-140 [41] and UTSA-120a [46] showed one of the highest selectivity of 1900 and ~600 for CO 2 in binary mixtures (CO 2 /N 2 ). Extremely high selectivity of 7531 for CO 2 /N 2 binary mixture was recorded for MOF MFUM-1(Cu) [139] without information on its adsorption capacity.…”

“…Polymer IHBPA (TEPA) [138] and PI-COF-2 [80] had adsorption capacities of 7.65 mmol/g and 5.8 mmol/g respectively at 1 bar and 298K while AC CuO NP-AC [108], ARG-K-Im [98] and DAC-AC-CO 2 [98] had adsorption capacities of 6.72 mmol/g, 5.63 mmol/g and 5.52 mmol/g respectively at 1 bar and 298K. MOF UTSA-120a [46] was the highest performing MOF in this regard with the adsorption capacity of 5.00 mmol/g at 1 bar and 296K; all other MOFs performed below this value in this study. This may be due to the incorporation of functional tetrazine groups into the structure, which improved its affinity for CO 2.…”

Adsorbents such as metal-organic frameworks (MOFs), polymers, activated carbon (AC), and membranes are becoming prominent for CO2, SO2, H2S and NH3 capture and in some cases, storage. Using the standard adsorbent properties (SAPs) such as adsorption capacity, selectivity, permeability/permeance, regenerability and reusability, ease of functionability and tunability, thermal and chemical stability, suitable candidates for noxious gas sequestration can be determined. To foster the development and selection of a more efficient adsorbent, proper documentation of adsorbent performance in terms of SAPs is crucial. In this study, a critical review of metal-organic framework (MOF), polymer, activated carbon (AC) and membrane adsorbents was performed. Using the SAPs, an up to date comparative analysis was done to select the best performing adsorbents. The results of the comparative analysis were then used to categorize the adsorbents' suitability for pre-combustion and post-combustion applications. A perspective of future study on adsorbents for noxious gas sequestration was also presented.
