Metal–organic frameworks (MOFs) are a group of porous materials that display potential in the elimination of toxic industrial compounds (TICs) from polluted water streams. However, their applications have so far been held up by issues due to their physical nature and cost. In this study, activated carbon (AC) is modified with an Fe-based MOF, iron terephthalate (Fe-BDC). A facile and cost-effective impregnation method is used for enhanced removal from aqueous solutions. The new adsorbent is characterized by SEM, FTIR, PXRD, and BET. The composite displays excellent uptake of Cr (VI) when compared to un-impregnated AC with a maximum monolayer adsorption capacity of 100 mg·g−1. The experimental data shows a high correlation to the Langmuir adsorption model. The adsorption kinetic study reveals that the adsorption of Cr (VI) to Fe-BDC@AC obeys the pseudo-first-order equation. The composite shows high reusability after five cycles and high adsorption rates reaching equilibrium in just 50 min. Such properties make the nanocomposite promising for water decontamination on larger scales compared to powder-based alternatives, such as individual MOF crystals.

“…690315 [ 40 ]. That diffraction pattern is in accordance with the work of [ 39 , 40 , 41 , 42 ]. Whereas Figure 3 also shows the diffraction pattern of Fe 3 O 4 metal oxide, which is the result of MOF FeBDC pyrolyzed at 500 °C for 1 h. The XRD peaks match well with the characteristic peaks of the inverse cubic spinel structure crystalline structure of Fe 3 O 4 in the International Centre for Diffraction Data (JCPDS-ICDD: 751610).…”

“…The decrease in mass that occurs at the temperature of 100–200 °C was caused by DMF solvents’ evaporation that is still contained in the FeBDC MOF powder. At 350–450 °C, a relatively significant mass loss was possibly caused by the decomposition of the hydroxyl group on the MOF surface and excessive water, followed by decomposition of BDC linker that was coordinated with metal ion core [ 38 , 39 , 40 ]. Besides, the transformation reaction involving recrystallization was indicated by an exothermic peak in the DTA curve.…”

Present-day science indicates that developing sensors with excellent sensitivity and selectivity for detecting early signs of diseases is highly desirable. Electrochemical sensors offer a method for detecting diseases that are simpler, faster, and more accurate than conventional laboratory analysis methods. Primarily, exploiting non-noble-metal nanomaterials with excellent conductivity and large surface area is still an area of active research due to its highly sensitive and selective catalysts for electrochemical detection in enzyme-free sensors. In this research, we successfully fabricate Metal-Organic Framework (MOF) FeBDC-derived Fe3O4 for non-enzymatic electrochemical detection of glucose. FeBDC synthesis was carried out using the solvothermal method. FeCl2.4H2O and Benzene-1,4-dicarboxylic acid (H2BDC) are used as precursors to form FeBDC. The materials were further characterized utilizing X-ray Powder Diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier-Transform Infrared Spectroscopy (FTIR). The resulting MOF yields good crystallinity and micro-rod like morphology. Electrochemical properties were tested using Cyclic Voltammetry (CV) and Differential Pulse Voltammetry (DPV) with a 0.1 M of Phosphate Buffer Saline (PBS pH 7.4) solution as the supporting electrolyte. The measurement results show the reduction and oxidation peaks in the CV curve of FeBDC, as well as Fe3O4. Pyrolysis of FeBDC to Fe3O4 increases the peak of oxidation and reduction currents. The Fe3O4 sample obtained has a sensitivity of 4.67 µA mM−1.cm−2, a linear range between 0.0 to 9.0 mM, and a glucose detection limit of 15.70 µM.

“…The construction of MOFs under mild hydrothermal conditions holds promise for the advanced industrialization of these materials. Thus, we synthesized for the first time Fe-MOF, Zr-MOF and Al-MOF in water from the prepared DST at room temperature and compared them to the ones synthesized at high temperature using the well-known protocol for the synthesis of MOFs (UiO-66 and MIL-101(Fe or Al)) as described in the literature [29][30][31][32][33] and are labeled as 110 1C for Fe-MOF, 120 1C for Zr-MOF and 220 1C for Al-MOF.…”
