“…Figure 1a shows the characteristic XRD patterns of a semi-crystalline Basolite ® F300 material. Broad peaks occur most notably at 2θ = 11, 14, 19, and 24 • , and are consistent with the peaks identified in literature of synthesized Fe-BTC MOF [24,25]. Figure 1b illustrates the nitrogen adsorption desorption isotherms of Basolite ® F300 with a shape characteristic of a mesoporous material with a type IV isotherm [26].…”

“…The average pore width demonstrates a dominance of smaller mesopores and falls within the 2-50 nm range, confirming the mesoporous nature of the Basolite ® F300 material [26]. Additionally, the material demonstrated a high BET surface area of 1465 m 2 /g falling near reported ranges of 800-1400 m 2 /g for either Basolite ® F300 or various synthesized Fe-BTC material [24,[27][28][29]. It has also been reported by manufacturers that the Basolite ® F300 surface area is expected to fall within a higher surface area range of 1300-1600 m 2 /g [30].…”

This study explores the use of the iron-containing metal–organic framework (MOF), Basolite®F300, as a heterogeneous catalyst for electrochemically-driven Fenton processes. Electrochemical advanced oxidation processes (EAOPs) have shown promise on the abatement of recalcitrant organic pollutants such as pharmaceuticals. Tetracyclines (TC) are a frequently used class of antibiotics that are now polluting surface water and groundwater sources worldwide. Acknowledging the fast capability of EAOPs to treat persistent pharmaceutical pollutants, we propose an electrochemical Fenton treatment process that is catalyzed by the use of a commercially available MOF material to degrade TC. The efficiency of H2O2 generation in the IrO2/carbon felt setup is highlighted. However, electrochemical oxidation with H2O2 production (ECO-H2O2) alone is not enough to achieve complete TC removal, attributed to the formation of weak oxidant species. Incorporating Basolite®F300 in the heterogeneous electro-Fenton (HEF) process results in complete TC removal within 40 min, showcasing its efficacy. Additionally, this study explores the effect of varying MOF concentrations, indicating optimal removal rates at 100 mg L−1 due to a balance of kinetics and limitation of active sites of the catalysts. Furthermore, the impact of the applied current on TC removal is investigated, revealing a proportional relationship between current and removal rates. The analysis of energy efficiency emphasizes 50 mA as the optimal current, however, balancing removal efficiency with electrical energy consumption. This work highlights the potential of Basolite®F300 as an effective catalyst in the HEF process for pollutant abatement, providing valuable insights into optimizing electrified water treatment applications with MOF nanomaterials to treat organic pollutants.

“…C-O stretching vibrations were represented by the peak at 1025.2 cm -1 , and broad peaks between 3800 -3000 cm -1 indicated the presence of hydroxyl groups in adsorbed water molecules. For the SA@Fe-BTC sample, peaks at 711.6 cm -1 , 760.5 cm -1 , 1380 cm -1 , 1448 cm -1 , 1577 cm -1 , and 1627 cm -1 were identified, indicating carboxylic (COO) asymmetric and symmetric stretching vibrations, (C-O) from the BTC ligand, and Fe-O bond vibrations [13,14]. In the FTIR spectrum of SA@ZIF-8 beads, O-H vibrations of alginate were seen at 3140 cm -1 , with stretching vibrations of aliphatic C-H at 2910 cm -1 .…”

In the present study, we examine the adsorption of the cationic dye Malachite Green (MG) onto two metal-organic frameworks: ZIF-8 and Fe-BTC. The preparation of beads was effectively carried out through the polymer coating process utilizing sodium alginate. To study the effect of different factors on adsorption capacity and removal %age of Malachite Green in a batch process, we employed a 2 3 factorial design study analysis. The investigation involved three primary factors, each with two levels: MOF type (A: Fe-BTC and ZIF-8), MOF bead dosage (B: 50 mg to 100 mg), and initial concentration (C: 5 mg/L to 17 mg/L). The primary effects of these variables and their interactions were examined using Response Surface Methodology (RSM), main effect, interaction effect, and Pareto chart. The factorial design analysis, conducted using analysis of variance (ANOVA), revealed that the most significant factor influencing adsorption capacity was the initial concentration of MG, followed by the dosage of MOF beads and the type of MOFs.

The effects of aging of colloidal dispersions of iron (Fe) oxy(hydr)oxides have practical implications for a variety of fields, including medicine, biology, chemistry, and environmental science. Aging affects the stability of these materials under different environmental conditions, thereby affecting their reactivity and applicability in remediation. However, only a limited number of studies have focused on aging-induced changes in the phase composition, surface properties, and toxicological effects of nanoparticles (NPs). In this study, a variety of Fe oxides were synthesized, including the closely related Fe oxides magnetite and maghemite, intermediate phases (Fe3-δO4: Fe3O4, γ-Fe2O3, 5Fe2O3∙9H2O), and δ-FeOOH. Fe3O4 was synthesized by precipitation, γ-Fe2O3 by direct oxidation of Fe3O4, while 5Fe2O3∙9H2O and δ-FeOOH were prepared by precipitation with slow and fast oxidation, respectively. The crystal structure, surface charge, and leaching of Fe ions of these materials were measured. All synthesized materials were then tested in bioassays with ciliates and higher plants at circumneutral pH, both upon preparation and after aqueous aging. Quantitative analysis of the XRD data using the Rietveld method showed that the crystal structure of the magnetite nanoparticles changed to γ-Fe2O3. The evaluation of biological activity in Sinapis alba (white mustard) showed that NPs of different compositions, stored at a maximum concentration of 10 g L-1, inhibited root growth by 50%. In the case of δ-FeOOH and Fe3O4, however, concentrations of 1 g L-1 caused only minor inhibition. The toxic effects of Fe-NPs, attributed to the release of Fe2+ and Fe3+ ions by oxidation, were found to be consistent with the redox behavior of NPs. The study of the properties of magnetic nanoparticles, both in their initial state and after aqueous aging, enhances our understanding of their performance in magnetic nanofluids.
