In this paper, the effect of conventional solvothermal and a microwave-assisted method for the synthesis of MIL-101(Fe) and NH 2 -MIL-101(Fe) as adsorbents for the removal of tetracycline in wastewater is reported for the first time. The results had shown that the microwave treatment led to a significant reduction in the material synthesis time, which greatly saved the energy. It was also found that the microwave-assisted synthesized material exhibited small particle size, high specific surface area and better adsorption capacity. The introduction of amino group further enhanced the adsorption capacity of MIL-101(Fe). The adsorption capacity of MIL-101(Fe) and NH 2 -MIL-101(Fe) samples for tetracycline adsorption by microwave assisted synthesis method reached up to 332 mg/g and 378 mg/g, respectively. Moreover, the adsorption isotherm was well-fit with Freundlich model, indicating a multilayer adsorption . The kinetic studies indicated that the reaction followed pseudo second-order reaction kinetics with a best fit to the theoretical value. Due to the higher adsorption efficiency and lower energy consumption of the synthesis, the as-prepared microwave assisted materials could be used as potential adsorbents for different pollutants in wastewater.

MIL-101 is a promising adsorbent because of its large pore volume, high separation selectivity, easy regeneration, and good stability. MIL-101 was synthesized and characterized by X-ray diffraction, scanning electron microscopy, and nitrogen adsorption at 77 K. Adsorption isotherms of pure N2, CH4, and CO2 were measured on MIL-101 from 263 K to 313 K and at pressures up to 0.8 MPa. The Langmuir model was a good fit for the experimental isotherms and the isosteric heats of adsorption decreased in the order: CO2 > CH4 > N2. The CO2/CH4 separation selectivity was sensitive to the adsorption pressure and temperature and it varied from 3.2 to 6.3. In contrast, the CH4/N2 separation selectivity changed from 2.6 to 3.3 with temperature and pressure.

Nanomaterial technology has attracted much attention because of its antibacterial and drug delivery properties, among other applications. Metal-organic frameworks (MOFs) have advantages, such as their pore structure, large specific surface area, open metal sites, and chemical stability, over other nanomaterials, enabling better drug encapsulation and adsorption. In two examples, we used the common pathogenic bacteriumStaphylococcus aureusand highly infectious influenza A virus. A novel complex MIL-101(Fe)-T705 was formed by synthesizing MOF material MIL-101(Fe) with the drug favipiravir (T-705), and a hot solvent synthesis method was applied to investigate the in vitro antibacterial and antiviral activities. The results showed that MIL-101(Fe)-T705 combined the advantages of nanomaterials and drugs and could inhibit the growth ofStaphylococcus aureusat a concentration of 0.0032 g/mL. Regarding the inhibition of influenza A virus, MIL-101(Fe)-T705 showed good biosafety at 12, 24, 48, and 72 h in addition to a good antiviral effect at concentrations of 0.1, 0.2, 0.4, 0.8, 1.6, and 3 μg/mL, which were higher than MIL-101(Fe) and T-705.Keywords:MIL-101(Fe);favipiravir;antibacteria;antiviral

With the booming development of the new energy industry, the demand for lithium resources has increased dramatically. Adsorption is a green and inexpensive process for lithium extraction from saline lakes but current commercial adsorbents generally have low adsorption capacity and poor stability, and are difficult to be applied to the purification of high-concentration lithium salts. Herein, we report an adsorbent, sulfonate-modified MIL-101(Cr) (MIL-101(Cr)-SO 3 H), for the efficient extraction of lithium from brine and highly concentrated lithium solution. It has high adsorption capacity (118.2 mg g −1 ) on Li + adsorption and fast kinetics (3.5 h to achieve full adsorption equilibrium). Detailed investigations clarify that the adsorption follows the Freundlich model in a spontaneous manner. The adsorption mechanisms of MIL-101(Cr)-SO 3 H for Li⁺ primarily include physical adsorption, chemical adsorption, and functional group adsorption. Such capacity is demonstrated with high durability and selectivity, indicating MIL-101(Cr)-SO 3 H is a promising adsorbent for Li + recycling and extraction.

CH 3 Hg + in water is a neurotoxin that is difficult to eliminate and is readily absorbed by the human body through food chains. In this study, thioctic acid was grafted onto the surface of NH 2 -MIL-101 via an amidation reaction to prepare an adsorption material for the rapid and effective removal of CH 3 Hg + , which is designated as LA-MIL-101.The synthesis of LA-MIL-101 was confirmed through analyses including FT-IR, XRD, SEM, TGA, and XPS. BET results indicate that the specific surface area of LA-MIL-101 is 464.92 m 2 ·g −1 . The ideal conditions for CH 3 Hg + adsorption were explored by varying environmental factors such as pH, contact time, and temperature. Furthermore, the introduction of sulfur significantly enhanced the adsorption capacity for CH 3 Hg + . Batch adsorption experiments demonstrate that LA-MIL-101 exhibits an exceptionally rapid adsorption rate, achieving over 88.3 % of the total removal rate within just one minute. Additionally, LA-MIL-101 shows remarkable adsorption efficacy across a broad pH range. The adsorption behavior of LA-MIL-101 for CH 3 Hg + aligns with the Elovich and Langmuir models, with a maximum adsorption capacity reaching 1391.77 μg·g −1 . LA-MIL-101 also displays a strong anti-interference capability in environments containing humic acid or Na + . Notably, it maintains high removal efficiency under conditions involving coexisting cations, as well as in simulated surface water, simulated groundwater, and natural seawater. Moreover, LA-MIL-101 demonstrates good stability and recyclability, retaining effective adsorption after five adsorption/desorption cycles. XPS results elucidate the adsorption mechanism of CH 3 Hg + , highlighting interactions with sulfur (S) and nitrogen (N) atoms. Overall, LA-MIL-101 exhibits high practicality and significant potential for application in the emergency treatment of CH 3 Hg + in aquatic environments.

The pollution of aromatic organophosphorus flame retardants (aromatic OPFRs) in aquatic environments has drawn great attention over the last few years. Two MIL-101-based metal–organic frameworks (Cr-MIL-101 and Fe-MIL-101-NH2) which possess ordered mesoporous cavities (2.9 and 3.4 nm) and aromatic structures were chosen and prepared to selectively adsorb a typical aromatic OPFR [triphenyl phosphate (TPhP)] from aqueous solution. Pore distribution analysis showed that Cr-MIL-101 and Fe-MIL-101-NH2 had both a mesoporous structure (2–3.5 nm) and microporous structure (1–2 nm), conducive to diffusion and adsorption of TPhP molecules. Compared with Fe-MIL-101-NH2 as well as commercial activated carbon, Cr-MIL-101 showed rapid and efficient adsorption for TPhP, and its initial sorption velocity (v0) calculated from the pseudo-second-order model was up to 568.18 μmol g−1 h−1. The adsorption equilibrium of TPhP on the Cr-MIL-101 was almost achieved within 12 h, while the equilibrium time of other adsorbents required more than 48 h. The study of selective adsorption found that Cr-MIL-101 had a higher sorption amount for aromatic OPFRs than alkyl-OPFRs and other aromatic compounds with different chemical structures. Cr-MIL-101 was able to keep a steady selective adsorption for TPhP in the presence of co-existing aromatic compounds. Based on the analysis of Kow, molecular structure and further density functional theory calculations, hydrophobic interactions may play a dominant role in the selective adsorption process of TPhP, and π–π interactions may be also involved. Cr-MIL-101 exhibits reusability and promising potential to rapidly and selectively remove aromatic OPFR in environmental remediation.

MIL-101 (Cr) was synthesized by a hydrothermal method and used as support to prepare a series of polyethylenimine (PEI) incorporated MIL-101 (Cr) by wet impregnation method. All characterization results revealed that the structure of MIL-101 (Cr) was well-maintained by the incorporation of polyethylenimine and confirmed the presence of PEI within MIL-101 (Cr). The CO 2 adsorption studies were carried out in a fixed bed reactor from 30 to 90 °C, 1 bar. The adsorption of CO 2 has been increased by the incorporation of PEI. It was due to the chemical interaction between the NH 2 and CO 2 groups to form a carbamate. The high CO 2 adsorption capacity 3.81 mmol g −1 was shown by 70 wt% PEI loaded MIL-101 (Cr) at 75 °C, 1 bar, because of more number of NH 2 groups and a high number of CO 2 molecules diffusion. Its adsorption capacity was 4.7 times higher than the adsorption capacity of MIL-101 (Cr) (0.80 mmol g −1 ). Moreover, in moisture condition, CO 2 adsorption capacity was increased to 4.4 mmol g −1 by the formation of ammonium bicarbonate and showed good adsorption stability throughout each adsorption-desorption cycle. The Avrami adsorption kinetic model was well fitted with experimental breakthrough CO 2 adsorption data of MIL-101 (Cr)-PEI-70. It suggested that the adsorption of CO 2 on PEI incorporated material was chemical adsorption.

Background Melanoma is an aggressive form of skin cancer, and single-modality treatments often fail to prevent tumor recurrence and metastasis. Combination therapy has emerged as an effective approach to improve treatment outcomes.Methods In this study, we developed a multifunctional nanoplatform, MIL@DOX@ICG, utilizing MIL-101-NH2(Fe) as a carrier to co-deliver the chemotherapeutic agent doxorubicin (DOX) and the photosensitizer indocyanine green (ICG). MIL-101-NH2(Fe) was synthesized via a hydrothermal method. Drug release was evaluated under different pH conditions, and the photothermal effect was tested under near-infrared (NIR) laser irradiation. Hydroxyl radical and reactive oxygen species generation capacities were quantified. Cellular studies using B16F10 cells assessed cytotoxicity, cellular uptake, migration inhibition, and colony formation suppression. In vivo experiments in melanoma-bearing mice evaluated antitumor efficacy and systemic safety through tumor growth inhibition, histological analyses, and toxicity assessments.Results MIL@DOX@ICG exhibited a uniform octahedral structure with a particle size of approximately 139 nm and high drug loading efficiencies for DOX (33.70%) and ICG (30.59%). The nanoplatform demonstrated pH-responsive drug release and potent photothermal effects. The generation of hydroxyl radicals via the Fenton reaction and reactive oxygen species production under NIR laser irradiation by MIL@DOX@ICG were confirmed. In vitro assessments revealed significant cytotoxicity of MIL@DOX@ICG against B16F10 cells under NIR laser irradiation, with improved efficacy in inhibiting cell proliferation and migration. In vivo studies confirmed the superior antitumor efficacy of MIL@DOX@ICG + NIR treatment, synergistically harnessing chemotherapy, photothermal therapy, photodynamic therapy, and chemodynamic therapy effects while maintaining excellent biocompatibility.Conclusion Our findings underscore the potential of MIL-101-NH2(Fe) nanoparticles as a versatile and effective platform for synergistic melanoma therapy, offering a promising strategy for overcoming the limitations of conventional treatment modalities.

MIL-101(Fe) was explored for the first time for the catalytic conversion of glucose into lactic acid (LA). The as-synthesized MIL-101(Fe) was successfully characterized, and its higher specific surface area, porosity, and feasible acid properties were confirmed to determine the remarkable catalytic activity in glucose-to-LA conversion (up to 25.4% yield) compared with other catalysts like MIL-101(Cr, Al) and UiO-66(Zr). The reaction parameters including temperature, reaction time, and substrate species as well as catalyst reusability were discussed.

MIL-101(Cr), one of the best investigated and widely used metal–organic frameworks, has been easily synthesized with particle diameters in the range from 387(28) nm to 90(10) nm by using acetic acid as a modulator . The particle size of MIL-101(Cr) decreased with increasing acetic acid concentration. The decrease of size in high concentration of acetic acid may be explained with the efficient suppression of the framework extension. In a selected condition, MIL-101(Cr) possessing an average diameter of about 90 nm can be prepared easily and reproducibly in gram-scale, with high BET-surface areas (3200–3500 m 2 /g) and fairly good yield (60–75%).
