“…In addition to the detection, MOFs have also been widely employed in photocatalysis, like water splitting, CO 2 reduction, organic reactions and so on [ 15 , 16 , 17 , 18 , 19 , 20 ]. The removal of organic pollutants in the waste water is a significant project with the methods like adsorption and in situ degradation [ 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Among the common pollutants, organic dyes are widely utilized in industrial production, which is in large dosage and strong persistence in the environment resulting in harm to human kidneys and organs [ 28 ].…”

Metal-organic frameworks (MOFs) have presented potential for detection of specific species and catalytic application due to their diverse framework structures and functionalities. In this work, two novel pillar-layered MOFs [Cd6(DPA)2(NTB)4(H2O)4]n·n(DPA·5DMA·H2O) (1) and [Cu2(DPA)(OBA)2]n·n(2.5DMF·H2O) (2) [DPA = 2,5-di(pyridin-4-yl)aniline, H3NTB = 4,4′,4′′-nitrilotribenzoic acid, H2OBA = 4,4′-oxydibenzoic acid, DMA = N,N-dimethylacetamide, DMF = N,N-dimethylformamide] were successfully synthesized and structurally characterized. Both 1 and 2 have three-dimensional framework structures. The fluorescent property of 1 makes it possible for sensing specific amino acid such as L-glutamic acid (Glu) and L-aspartic acid (Asp). While MOF 2 was found to be suitable for photocatalytic degradation of Rhodamine B (RhB) in the presence of H2O2. The results imply that MOFs are versatile and metal centers are important in determining their properties.

“…The peaks at 470 and 535 cm −1 were assigned to uniform deformation modes of Zn–O and W–O bonds in ZnO 6 and WO 6 octahedrons, respectively [ 29 ]. In addition, the bands of the O–H stretch and H–O–H bending vibrations were located at 3432 and 1632 cm −1 , which revealed that the synthesized samples contained a notable amount of some structural water and surface-adsorbed water [ 30 , 31 ]. In the fingerprint region, the absorption bands at 535 cm −1 corresponded to the NiO 6 polyhedral in the crystal structure of NiWO 4 , 880 and 830 cm −1 were due to the vibration of the WO 2 entity present in W 2 O 8 group, and 710 and 615 cm −1 were due to the typical two oxygen bridge (W 2 O 8 ) − asymmetric stretching units [ 32 ].…”

Fluorometric Sensing and Detection of p-Nitroaniline by Mixed Metal (Zn, Ni) Tungstate Nanocomposite

Aromatic amines are important chemical intermediates that hold an irreplaceable significance for synthesizing many chemical products. However, they may react with substances excreted from human bodies to generate blood poisoning, skin eczema, and dermatitis disease and even induce cancer-causing high risks to human health and the environment. Metal tungstates have been proven to be highly efficient materials for developing various toxic gases or chemical detection sensor systems. However, the major factors of the sensors, such as sensitivity, selectivity, stability, response, and recovery times, still need to be optimized for practical technological applications. In this work, Ni-doped ZnWO4 mixed metal tungstate nanocomposite material was synthesized by the hydrothermal method and explored as a sensor for the fluorometric determination of p-nitroaniline (p-NA). Transmission electron microscopy (TEM) was used for the elucidation of the optimized particle diameter. Scanning electron microscopy (SEM) was employed to observe the surface morphological changes in the material during the solid-state reactions. The vibration modes of as-prepared samples were analyzed using Fourier-transform infrared spectroscopy (FTIR). The chemical bonding and oxidation states of individual elements involved in material synthesis were observed using X-ray photoelectron spectroscopy (XPS). The PL activities of the metal tungstate nanoparticles were investigated for the sensing of p-nitroaniline (p-NA). The obtained results demonstrated that ZnNiWO4 was more effective in sensing p-NA than the other precursors were by using the quenching effect. The material showed remarkably high sensitivity towards p-NA in a concentration range of 25–1000 μM, and the limit of detection (LOD) value was found to be 1.93 × 10−8 M for ZnWO4, 2.17 × 10−8 M for NiWO4, and 2.98 × 10−8 M for ZnNiWO4, respectively.

“…Metal-organic frameworks (MOFs) are fascinating porous coordination polymers (CPs), which are made up of organic ligands and metallic cations or metal-containing nodes [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Owing to their high intermolecular pores, specific surface area, unsaturated active metal sites, and structural and functional diversities [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ], they have adopted a critical interest in various fields, such as energy storage, ion exchange, sensors, drug delivery/release, separation, molecular recognition, catalysis and theranostics [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 ].

“…Compared with some traditional materials such as porous zeolite materials, polymers, and other materials [ 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 ], MOFs have a specific surface area and volume, a tunable pore size, and a better biocompatibility [ 57 , 58 , 59 ], which make them an ideal candidate for antimicrobial activity and cancer therapy, and so on [ 60 , 61 , 62 , 63 , 64 ]. In addition, MOF porosities and compositions can be tweaked by carefully choosing organic components and metal ions to achieve precise physical and chemical features [ 39 , 65 , 66 , 67 , 68 , 69 ]; and nanoscale MOFs have remarkable loading capacities, which are good for drug loading [ 39 , 40 , 70 , 71 , 72 , 73 , 74 , 75 , 76 ].…”

With the continuous evolution of bacteria and the constant use of traditional antibiotics, the emergence of drug-resistant bacteria and super viruses has attracted worldwide attention. Antimicrobial therapy has become the most popular and important research field at present. Coordination Polymer (CP) and/or metal-organic framework (MOF) platforms have the advantages of a high biocompatibility, biodegradability, and non-toxicity, have a great antibacterial potential and have been widely used in antibacterial treatment. This paper reviewed the mechanism and antibacterial effect of three typical MOFs (pure Ag-MOFs, hybrid Ag-MOFs, and Ag-containing-polymer @MOFs) in silver-based coordination polymers. At the same time, the existing shortcomings and future views are briefly discussed. The study on the antibacterial efficacy and mechanism of Ag-MOFs can provide a better basis for its clinical application and, meanwhile, open up a novel strategy for the preparation of more advanced Ag-contained materials with antibacterial characteristics.
