Case Study

MIL-100(Fe) for the Preparation of Photocatalysts AgI/MIL-100(Fe) via Solution Method

Wang Q, et al. Applied Surface Science, 2023, 616, 156528.

MIL-100(Fe) can be used to prepare AgI/MIL-100(Fe) composites through a simple solution method. These composites exhibit excellent photocatalytic redox activity and stability.
Synthesis Method
1.Add MIL-100(Fe) to a solution containing KI (0.11 mol/L).
2.Stir the mixture for 1 hour.
3.Add an aqueous solution of AgNO₃ (1.00 mol/L) dropwise to the mixture.
4.Stir the mixture at room temperature for 12 hours.
5.Collect the product by filtration.
6.Wash the product thoroughly several times with deionized water.
7.Dry the product under vacuum at 60°C to obtain the AgI/MIL-100(Fe) composite.
Photocatalytic Activity
When the mass ratio of AgI to MIL-100(Fe) was 1:10 (referred to as AM-10), it exhibited the best photocatalytic activity for Cr(VI) reduction. Under LED light irradiation, Cr(VI) could be completely reduced within 75 minutes. The reduction rate of Cr(VI) by AM-10 was 15.3 times higher than that of AgI and 2.6 times higher than that of MIL-100(Fe). AM-10 also maintained good stability after five cycles of Cr(VI) reduction and could completely kill 10⁷ CFU/mL of Escherichia coli and Staphylococcus aureus within 45 minutes.

MIL-100(Fe) as a Functional Filler to Prepare pH-responsive Smart Membranes with Amine Sensitivity

Huang K, et al. International Journal of Biological Macromolecules, 2024, 270, 132463.

MIL-100(Fe) exhibits amine adsorption properties and can be incorporated into anthocyanin/pectin membranes as a functional filler to enhance their physical properties (p < 0.05). The inclusion of MIL-100(Fe) improves the membranes' sensitivity to amines through chemical adsorption, making them effective for monitoring the freshness of chilled meat.
Preparation of ANs@MIL/P Films
The smart films were prepared using a casting method:
1.Dissolve 3 g of pectin and 1.5 g of anthocyanins (ANs) in 100 mL of deionized water.
2.Add different amounts of MIL-100(Fe) (0, 1, 2, and 3 wt% based on pectin) to the solution.
3.Stir the mixture magnetically at 40°C for 30 minutes until all additives are fully dispersed.
4.Add 2 g of glycerol as a plasticizer.
5.Pour 25 mL of the casting solution into a Petri dish and dry for 12 hours (40% RH, 45°C).
6.The resulting films were designated as ANs/P, ANs@MIL-1/P, ANs@MIL-2/P, and ANs@MIL-3/P.
Results and Benefits
The study found that an appropriate amount of MIL-100(Fe) (≤2%) was uniformly dispersed within the film. The addition of MIL-100(Fe) improved the mechanical properties, barrier properties, and thermal stability of the smart film. The sensitivity of the film to ammonia was enhanced through a combination of chemical adsorption and intraparticle diffusion.
Importantly, the ANs@MIL/P film demonstrated amine-sensitive properties, accurately indicating the freshness of meat (fresh, sub-fresh, and spoiled). This study preliminarily explored the enhancement of adsorption properties in smart films by MIL-100(Fe), which can potentially be combined with artificial intelligence to model and predict the spoilage stage of chilled meat.

MIL-100(Fe) used to Enhance the Tartrazine Sensing Ability of PEDOT Modified Electrodes

Wu SY, et al. Journal of the Taiwan Institute of Chemical Engineers, 2024, 155, 105254.

MIL-100(Fe) is used to improve the tartrazine sensing ability of poly(3,4-ethylenedioxythiophene) (PEDOT)-modified electrodes. MIL-100(Fe) is an effective absorber for the synthetic azo dye tartrazine (TT), and its immobilization on PEDOT enhances the sensitivity of PEDOT/Pt electrodes towards tartrazine detection. The MIL-100(Fe)/PEDOT/Pt electrode demonstrates significant sensitivity to TT.
Preparation of MIL-100(Fe)/PEDOT/Pt Electrode
Electrode Preparation:
Remove surface wax from Pt wires (15 mm length, 0.6 mm diameter).
Immerse 10 mm of Pt wires in solutions containing 0.1 M LiClO4, 0.01 M EDOT, or PSS.
First Layer Synthesis (PEDOT):
Polymerize PEDOT on a bare Pt electrode using cyclic voltammetry.
Use a platinum counter electrode and an Ag/AgCl (in 3 M NaCl) reference electrode.
Perform 10 scan cycles within a potential range of 0.0 to 1.0 V at a scan rate of 0.01 V/s.
Remove the residual solution and air-dry the electrode.
Second Layer Synthesis (PEDOT/MOF):
Mix 6 mL of 0.1 M LiClO4 and 0.01 M EDOT monomer solutions with 1 mL of 0.1 g/mL MIL-100(Fe) solution.
Use the PEDOT/Pt electrode as the working electrode.
Synthesize the second layer of PEDOT (MOF) on the PEDOT/Pt electrode using the same polymerization parameters via the CV method.
The result is a PEDOT-MIL-100(Fe)/Pt or PEDOT(MOF)/Pt electrode, which shows enhanced sensitivity to tartrazine due to the presence of MIL-100(Fe).

MIL-100(Fe) for the Synthesis of Ag@MIL-100(Fe) Composites via Gamma Ray Irradiation Method

Rattanakit P, et al. South African Journal of Chemical Engineering, 2024, 47, 270-278.

Ag@MIL-100(Fe) composites were successfully synthesised by doping ultrafine AgNPs into the structure of MIL-100(Fe) using gamma-ray irradiation. The prepared Ag@MIL-100(Fe) proved to be an effective catalyst for the degradation of methyl orange dye, with the reaction rate and efficiency dependent on the Ag content and the gamma irradiation dose. The incorporation of AgNPs into the MOF enhances the catalytic activity for methyl orange degradation, indicating potential applications in catalysis and environmental remediation.
Preparation of Ag@MIL-100(Fe)
Preparation of Silver Nitrate Solution: Dissolve 375 mg of AgNO3 in a mixture of 750 µL MilliQ water and 450 µL ethanol.
Doping Procedure:
Transfer the silver nitrate solution to a glass vial containing 150.0 mg of MIL-100(Fe).
Achieve homogeneity by sonication of the mixture for 5 minutes at room temperature.
Perform a 20-minute nitrogen purge, followed by 5 minutes of sonication and 1 minute of shaking to ensure adequate mixing.
Gamma Irradiation: Place the reaction vessel in a cobalt-60 gamma irradiator. Irradiate the sample with target total doses of 1 and 10 kGy at a dose rate of 1.7 kGy/h.
Post-Irradiation Processing:
Immediately after irradiation, rinse the Ag@MIL-100(Fe) crystals with ethanol and acetone to remove any remaining excess silver salts.
Dry the samples at 150°C for 12 hours.
Store the dried samples in a desiccator.
The resulting Ag@MIL-100(Fe) composites show enhanced catalytic activity for the degradation of methyl orange, with potential applications in catalysis and environmental remediation.

MIL-100(Fe) for the Synthesis of pH Responsive Malononitrile Functionalized MOF

Das A, et al. Chemosphere, 2024, 348, 140780.

MIL-100(Fe) can be used to synthesize a pH-responsive malononitrile-functionalized metal-organic framework, MIL-100(Fe)_MN, for the efficient adsorption of uranium U(VI) in real alkaline leachate. The porous structure of MIL-100(Fe) is functionalized with malononitrile (MN) via an in situ Knoevenagel condensation reaction, which introduces abundant -C≡N groups on the surface of the adsorbent.
The preparation method of malononitrile-functionalized MIL-100(Fe) is as follows:
Malononitrile (2 g) and MIL-100(Fe) (0.4 g) were added to a beaker containing 70 mL of toluene, and the suspension was agitated at 30 °C for 40 hours to achieve a homogeneous dispersion. The crystalline particles were separated by centrifugation and washed five to six times with 30 mL of DMF. The precipitate was then activated by immersing it in 30 mL of CH₃OH for 72 hours, with fresh CH₃OH added every 24 hours. Finally, the resulting MIL-100(Fe)_MN was collected after overnight drying.
