“…In recent years, a considerable number of researchers have been committed to improving ADS for developing new MOF crystals by the replacement of substrate, [44][45] the employment of additional templates [46][47] and adding structure-directing agents. [48] Moreover, ADS has greatly helped to innovate the synthesis of MOFs (as well as their complexes) and broaden their practical applications.…”

ing new MOFs and developing novel eco-friendly electrochemical synthesis methods for MOFs' application in environmental analysis. Moreover, the applications of MOFs in environmental analysis field in recent years were comprehensively illustrated and the advantages and disadvantages of electrochemical synthesis methods to prepare MOFs as environmental analytical nanomaterials were evaluated. Finally, some suggestions for the optimization of electrochemical synthesis methods for MOFs and their future opportunities in environmental analytical applications were proposed.

“…Although studies on MOF films on various copper supports such as plates, disks, meshes, beads and copper coated silicon wafers, using gold and glass carbon electrodes, were reported, electrochemical deposition of MOFs directly on porous hollow fibers (HFs) have not been reported. Demirel et al [72] reported on the thin metal organic framework (Cu-BTC, (Cu 3 (BTC) 2 ,BTC =benzene-1,3,5-tricarboxylate) films on Cu-HFs, to study the effect of the presence of a supporting electrolyte and the magnitude of the applied electrical potential on the formation and the morphology of the films. In the presence of a supporting electrolyte, formation of less homogeneous films and the growth of MOF crystals were observed in the liquid, whereas, in the absence of a supporting electrolyte, and at low potential, more uniform films with smaller particles were obtained.…”

With the increase in demand for commodities in the world, it is advisable to conserve resources. In the case of liquid wastes generated from pharmaceutical and petroleum industries, an unconventional solution is provided for the regeneration of solvents. However, this solvent recovery can be carried out using various efficient methods. Recently, Mixed Matrix Membranes (MMM) obtained by the addition of nanoparticles into a polymer matrix as reinforcements, or using a material with a well-defined inorganic network as a membrane like zeolite, silica based, Zeolite imidazolate frameworks (ZIFs) and Metal organic frameworks (MOFs), were explored for a solvent recovery process. These membranes possess characteristics such as high selectivity, flux and stability at various environmental conditions for the solvent recovery process. In this review, we have covered the polymer, nanocomposites, and ceramic membranes for solvent recovery through the pervaporation and organic solvent nanofiltration processes. The key challenges faced by the materials such as MOFs, zeolite, silica, zeolite and ZIFs when they are fabricated (through in situ synthesis or secondary growth process) as membranes and separation of solvents to explore for the solvent recovery process are reviewed.

“…The electrochemical strategy makes use of the anodic oxidation or cathodic reduction reactions to trigger the crystallization of MOF materials. , In the anodic deposition, oxidation of metal electrodes of various types generates the corresponding metal ions, which subsequently react with organic ligands in the electrolytic solution to form MOF materials on the surface of anode. − In the cathodic deposition, the reduction of a probase (such as water, triethylammonium, and nitrates) on electrode causes an increase in pH nearby, which deprotonates organic ligands to trigger the formation of MOFs on the cathode surface. − Although the cathodic method does not limit electrode materials for MOFs to deposit as compared with the anodic one, it is commonly challenged by the accompanying plating of corresponding metals in the deposition of those MOFs that contain easily reduced metal ions (such as Zn 2+ and Cu 2+ ) due to the large reduction overpotentials of proton and nitrate ions in the probases above-mentioned. , One possible way to address this issue is to use special catalytic electrodes to lower the reduction overpotentials of nitrate ions and proton, for example, zinc for nitrate and platinum for triethylammonium. , Another approach is to seek a more readily reduced probase. In this regard, we demonstrated recently that O 2 can serve as an effective probase to suppress the plating of metallic zinc and cobalt in the electrodeposition of zeolitic imidazolate framework materials (ZIF-8, ZIF-67, and ZIF-71) .…”

Reductive deposition is an attractive strategy to prepare films of metal–organic frameworks (MOFs), but to cathodically deposit the intergrown dense films of MOFs containing readily reduced metal ions (e.g., Cu2+) without the plating of the corresponding metals still remains a significant challenge. Here, we report the cathodic deposition of metallic copper-free films of two copper-carboxylate MOFs (HKUST-1 and MOF-14). Our strategy relies on the utilization of O2 as probase to electrochemically trigger the crystallization of MOFs. Systematical cyclic voltammetry studies indicate that the favorable synergistic catalytic effects of the acidic copper ions and benzene-1,3,5-tricarboxylic acid ligands on the O2 reduction can positively shift the deposition potential of HKUST-1 significantly to +0.05 V (vs Ag/AgCl), avoiding effectively the plating of metallic copper and facilitating greatly the control over the crystallization kinetics of MOFs. By the further optimization of experimental conditions relevant to reaction temperature, supporting electrolyte, O2 concentration, and working potential, the intergrown dense MOF films with tunable thicknesses were deposited successfully on several commonly used electrodes including the highly oriented pyrolytic graphite, carbon fiber, carbon cloth, and fluorine-doped tin oxide.
