“…Ce(III)-BDC exhibits remarkable crystallinity without any impurity, as confirmed from the intensity of each of its diffraction peaks. The XRD profile of Ce(III)-BDC was found to be in close agreement with the previously reported Ce-MOFs, ,, indicating the successful synthesis of Ce(III)-BDC MOF. Also, the XRD patterns of the as-obtained sample prepared at room temperature showed the same reflection as the simulated or theoretical patterns (Figure ) of Ce 2 (BDC) 6 (H 2 O) 4 (CCDC 875876). , The XRD patterns appeared to be similar before and after the adsorption of the phosphate ion, indicating that the loaded anion does not change the crystalline nature of the material, which can be taken as an advantage for its recyclability.…”

The discharge of inorganic pollutants like phosphate and fluoride is a cause of mounting concern to the world due to the substantial environmental and human health risk. Adsorption is one of the most common and affordable technologies widely utilized for removing inorganic pollutants such as phosphate and fluoride anions. Investigating efficient sorbents for the adsorption of these pollutants is extremely important and challenging. This work aimed at studying the adsorption efficiency of the Ce(III)-BDC metal–organic framework (MOF) for the removal of these anions from an aqueous solution using a batch mode. Powder X-ray diffraction (XRD), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET), and scanning electron microscopy-energy dispersive X-ray analysis (SEM-EDX) techniques evidenced the successful synthesis of Ce(III)-BDC MOF in water as a solvent without any energy input within a short reaction time. The outstanding removal efficiency of phosphate and fluoride was exhibited at an optimized pH (3, 4), adsorbent dose (0.20, 0.35 g), contact time (3, 6 h), agitation speed (120, 100 rpm), and concentration (10, 15 ppm) for each ion, respectively. The experiment on the effect of coexisting ions demonstrated that SO4 2– and PO4 3– ions are the primary interfering ions in phosphate and fluoride adsorption, respectively, while the HCO3 – and Cl– ions were found to have interfered less. Furthermore, the isotherm experiment showed that the equilibrium data fitted well with the Langmuir isotherm model and the kinetic data correlated well with the pseudo-second-order model for both ions. The results of thermodynamic parameters such as ΔH°, ΔG°, and ΔS° evidenced an endothermic and spontaneous process. The regeneration of the adsorbent made using water and NaOH solution showed the easy regeneration of the sorbent Ce(III)-BDC MOF, which can be reused four times, revealing its potential application for the removal of these anions from aqueous environment.

“…Starting from the plastic waste, chemical recycling may proceed via different processes, including glycolysis, hydrolysis, and methanolysis-hydrolysis being the most interesting one for MOF synthesis since it results directly in terephthalic acid [39]. In the last years, several reports can be found on the use of PET as the ligand source for the sustainable production of different MOFs [40][41][42]. Of particular interest is the possibility of producing the TPA (also known as H 2 BDC) via PET hydrolysis and simultaneously form the MOF in a one-pot reaction, as reported by some authors [43,44].…”

Opportunities from Metal Organic Frameworks to Develop Porous Carbons Catalysts Involved in Fine Chemical Synthesis

In the last decade, MOFs have been proposed as precursors of functional porous carbons with enhanced catalytic performances by comparison with other traditional carbonaceous catalysts. This area is rapidly growing mainly because of the great structural diversity of MOFs offering almost infinite possibilities. MOFs can be considered as ideal platforms to prepare porous carbons with highly dispersed metallic species or even single-metal atoms under strictly controlled thermal conditions. This review briefly summarizes synthetic strategies to prepare MOFs and MOF-derived porous carbons. The main focus relies on the application of the MOF-derived porous carbons to fine chemical synthesis. Among the most explored reactions, the oxidation and reduction reactions are highlighted, although some examples of coupling and multicomponent reactions are also presented. However, the application of this type of catalyst in the green synthesis of biologically active heterocyclic compounds through cascade reactions is still a challenge.

“…One important aspect of evaluating fluorescent sensors is their anti-interference capability. 63 Therefore, the antiinterference ability of CPs 1 and 2 toward antibiotics was measured in water containing thiamphenicol (TAP), lincomycin (LIN), ampicillin (AMP), enoxacin (ENO), nadifloxacin (NF), Ca 2+ , Na + , SO 4 2− , and Cl − . According to Figure 5, the Moreover, the recycling experiments were examined.…”

Because the accurate and rapid detection of antibiotics and pH plays an important role in biological systems and environmental fields, developing suitable and efficient sensors that can simultaneously detect antibiotics and pH has become important. In this work, we successfully designed and synthesized two new one-dimensional coordination polymers based on the mixed ligands L [N,N′-bis(4-methylpyridin-4-yl)-2,6-naphthalene dicarboxylamide] and Hfor CP 1, and M = Ni for CP 2), which were structurally characterized by single-crystal X-ray diffraction, infrared spectroscopy, powder X-ray diffraction, and thermogravimetric analysis. CP 1 and CP 2 can be used as ultraversatile fluorescent sensors, which can sense erythromycin (ERY) and oxacillin (OXC) by turn-on fluorescent enhancement and detect furaltadone (FTD) via the turn-off fluorescent quenching effect, separately. The concentration ranges of different analytes sensed by CPs 1 and 2 were 0−0.046 and 0−0.069 mM for ERY, 0−0.04 and 0−0.028 mM for OXC, and 0−0.155 and 0−0.019 mM for FTD, respectively. Moreover, CP 2 can effectively sense pH, in both a wide pH range and the fine physiological range. The sensors have a rapid luminescence response, good recyclability, and excellent fluorescence stability. More importantly, they not only represent the first example of detecting ERY or OXC based on fluorescent CPs but also are the very rare ultraversatile fluorescent sensors. The fluorescent sensing mechanism for antibiotics and pH was discussed in detail.
