“…[43,44] In the region of 1300-700 cm À1 , several bands are observed, and they are assigned to the out-of-plane vibrations of BDC. [44,45] After adsorption of ammonia, the spectra of MOF-5 and MOF-5/GO1 and MOF-5/GO2 do not change. However, a slight modification is observed around 1600 cm À1 for MOF-5/GO3.…”

Composites of the metal‐organic framework (MOF), MOF‐5, and graphite oxide (GO) with different ratios of the two components are prepared and tested in ammonia removal under dry conditions. The parent and composite materials are characterized before and after exposure to ammonia by sorption of N2, X‐ray diffraction, thermal analyses, and FT‐IR spectroscopy. The results show a synergetic effect resulting in an increase in the ammonia uptake compared to the parent materials. It is linked to enhanced dispersive forces in the pore space of the composites. Additionally, ammonia interacts with zinc oxide tetrahedra via hydrogen bonding and is intercalated between the layers of GO. Retention of a large quantity of ammonia eventually leads to a collapse of the MOF‐5 structure in the composites. The effect resembles that observed when MOF‐5 is exposed to water. Taking into account the similarity of ammonia and water molecules, it is hypothesized that ammonia causes a destruction of the MOF‐5 and composite structure as a result of its hydrogen bonding with the zinc oxide clusters.

“…In Figure 1a, the bands of 1400-1767 cm −1 are referred to as carboxylic functional groups [18]. The carboxyl groups from free aromatic carboxylic acid were observed at 1656 cm −1 [19] on the as-synthesized sample; however, the peak was removed after heat activation, due to solvent extraction and heat treatment. For the as-synthesized samples activated at 200 • C, the band of 1430-1533 cm −1 was observed, indicating the presence of aminocarboxylate compounds that were coordinated with zirconium metal center by -CO 2 asymmetrical stretching with the peaks at 1497 and 1564 cm −1 or -CO 2 symmetrical stretching with the peaks at 1385 and 1424 cm −1 [18,20,21].…”

Amino-functionalized Zr-MOF (amino-Zr-MOF) was synthesized using 2-aminoterephthalic acid as an organic linker. The physicochemical properties of the material were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and N 2 adsorption to understand its crystalline structure, morphology, thermal stability, and porous structure. CO 2 adsorption isotherms on amino-Zr-MOF were obtained at 1 atm and at different temperatures. In addition, CO 2 and CH 4 adsorption at high pressure (up to 10 atm) was also measured. CO 2 adsorption capacity on amino-Zr-MOF was 9 mmol/g at 988 kPa, 0 • C, while CH 4 adsorption capacity was 3.7 mmol/g at 900 kPa, 0 • C. The heat of CO 2 adsorption on amino-Zr-MOF was estimated to be 29.4 kJ/mol. Continuous column tests of CO 2 adsorption were performed at different concentrations of CO 2 in nitrogen at 20 mL/min and 0.7 g adsorbent and total adsorbed amounts of CO 2 within the column during the breakthrough time were calculated to be 4.55, 5.26 and 4.37 mmol/g at 10%, 15% and 20%CO 2 , respectively.

“…These compounds are mostly based on metal carboxylates, sulfonates, and phosphonates and are intensively investigated due to their potential applications as sorbents, ion exchangers, catalysts, or charge-storage materials. [2,3] Porous hybrid compounds based on metal carboxylates [4][5][6] and phosphonates [7][8][9][10] have attracted widespread interest in the past few years. We are interested in the use of organic ligands containing two or more different functional groups for the synthesis of functionalized porous hybrid compounds or bimetallic hybrid systems.…”

Nickel cobaltite, a low cost and an environmentally friendly supercapacitive material, is deposited as a thin nanostructure of 3–5 nm nanocrystals into carbon aerogels, a mesoporous host template of high specific surface areas and high electric conductivities, with a two‐step wet chemistry process. This nickel cobaltite/carbon aerogel composite shows ultrahigh specific capacitances of around 1700 F g−1 at a scan rate of 25 mV s−1 within a potential window of −0.05 to 0.5 V in 1 M NaOH solutions. The composite also possesses an excellent high rate capability manifested by maintaining specific capacitances above 800 F g−1 at a high scan rate of 500 mV s−1, and an outstanding cycling stability demonstrated by a negligible 2.4% decay in specific capacitances after 2000 cycles. The success is attributable to the fuller utilization of nickel cobaltite for pseudocapacitance generation, made possible by the composite structure enabling well exposed nickel cobaltite to the electrolyte and easy transport of charge carriers, ions, and electrons, within the composite electrode.
