“…[20][21][22] MOF feature large specic surface area and well-ordered pore structure, meriting them extensive applications in such elds as catalysis, sensors, gas isolation and storage. 23 Compared with conventional porous inorganic materials, synthesis conditions of MOF are more moderate and their structures are more viable for modication. 24 Multi-walled carbon nanotubes (MWCNT) 25,26 feature relatively good conductivity and large specic area.…”

“…In general, the peaks at 600–1500 are attributed to the in-the-plane bending (995, 1146, 1168, and 1301 cm –1 ) and out-of-the plane bending (689 and 751 cm –1 ) of the imidazole ring in ZIF-67. Besides, the peaks at 1418 and 1450 cm –1 are ascribed to the entire ring stretching vibration. − The FTIR spectrum of DBPC@ZIF-67 contains the characteristic peaks of both DBPC and ZIF-67, which further confirms the successful loading of ZIF-67 on DBPC.…”

The problem of industrial wastewater treatment still poses a challenge to mankind. Congo red (CGR), a kind of organic dye contaminant, is widely used in textile, papermaking, and other industries, making it necessary to develop effective techniques to remove CGR from wastewater. Herein, ZIF-67 crystals with excellent performance were grown in situ on the surface and internal pore surface of the low-cost and high-stability diatomite-based porous ceramic (DBPC) by the nonuniform nucleation growth method, and the DBPC@ZIF-67 composite was characterized by XRD, FTIR, SEM, and EDS methods. Adsorption experiments of DBPC@ZIF-67 to CGR were carried out, and the results showed a theoretical maximum adsorption capacity of 1351.35 mg/g for CGR on DBPC@ZIF-67 and a removal efficiency of 95.53% for 10 mg/L CGR solution at 25 °C. The adsorption kinetics, adsorption isotherms, and adsorption thermodynamics of DBPC@ZIF-67 on CGR were studied using the quasi-first-order and quasi-second-order kinetic models and the Langmuir and Freundlich adsorption isothermal models. The effects of adsorbent dosage and pH value on the adsorption capacity were also investigated. Besides, the stability and recoverability of the composite were studied by adsorption−desorption experiments.

“…The peak of 1631 cm -1 relates to the Gu C=N stretch mode on the methylimidazole-ligand, whereas the peaks of 2931 and 2864 cm -1 to the C-H stretch mode [18]. The OH group (the interlayer and adsorbed water molecules) stretch has two peaks at 3420 and 1612 cm -1 [19].…”

Bimetallic Metal-Organic Frameworks (MOFs) have attracted significant interest due to its high specific surface area and tunable porosity, leading to high sensitivity and catalytic activity. Amorphous MOF presents many opportunities as new functional materials especially in electrochemical applications. In this preliminary study, we explored the preparation, properties, and applications of amorphous MOF. It studies on the characteristics of Ni/Co-MOF synthesized through self-template using uniform Ni-Co glycerate spheres. Nickel and cobalt are active electrode materials with similar properties and atomic radius, and have much possible coordination with ligands so that they can be found in many types of MOFs. In this work Ni-Co Glycerate, produced in powder form, was used as the source of metal ions, 2-methylimidazole (H-MeIM) as the ligand, as well as aquabidest and ethanol as the solvents. The MOF was produced in two-step processes i.e. glycerate formation with solvothermal and MOF formation at room temperature. From the XRD test, no peak was observed, showing that the Ni/Co-MOF is in an amorphous phase. The results of the Scanning Electron Microscope (SEM) analysis showed that the Ni/Co-MOF has spherical shape covered by nanosheets, confirming the amorphous state.
