Case Study

MIL-100(Cr) for the Preparation of PVDF/MIL-100(Cr) Hybrid Matrix Membranes via Phase Transition Method

Sagita F, et al. Journal of Hazardous Materials Letters, 2024, 5, 100107.

MIL-100(Cr) can be used to modify polyvinylidene fluoride (PVDF) to produce PVDF/MIL-100(Cr) mixed matrix membranes (MMMs) for the removal of Congo red (CR) dye. MIL-100(Cr) is a metal-organic framework known for its highly porous nature, large surface area, and good stability, making it an interesting material for membrane technology.
PVDF/MIL-100(Cr) hybrid matrix membranes are prepared using a phase transition method. The phase inversion technique is employed to fabricate the membrane. First, varied amounts of MIL-100(Cr) (0.25%, 0.5%, and 1% wt) are dissolved in dimethylacetamide (DMAc, 87.12 g/mol) and stirred for 60 minutes. Polyethylene glycol (PEG 400) and PVDF powder are then added to the solution and stirred at 60°C for 24 hours. The mixture is subsequently sonicated for 1.5 hours at 60°C. Finally, the prepared polymer solution is cast onto a suitable support and soaked in a coagulation bath containing deionized water.

Synthesis of Ethylenediamine-Based MOFs Using MIL-100(Cr)

Sepehrmansouri H, et al. Molecular Catalysis, 2020, 481, 110303.

MIL-100(Cr) can be utilized to prepare ethylenediamine (En)-based metal-organic frameworks (MOFs), specifically En/MIL-100(Cr), which contain phosphorous acid tags. This En/MIL-100(Cr) can be further synthesized into a multilinker phosphorous acid-anchored En/MIL-100(Cr), forming a novel nanoporous catalyst.
Synthesis Steps
Grafting of Ethylenediamine onto MIL-100(Cr) to Obtain En/MIL-100(Cr):
Activate 0.1 g of MIL-100(Cr) at 200°C for 2 hours.
Suspend the activated MIL-100(Cr) in 10 mL of ultra-dry toluene.
Add 1 mL of ethylenediamine to the suspension.
Stir the mixture for 16 hours under an argon atmosphere to promote amine grafting.
Collect the resulting En/MIL-100(Cr) solid by filtration.
Wash the solid several times with acetone.
Preparation of MIL-100(Cr)/NHEtN(CH₂PO₃H₂)₂:
Combine 1 g of En/MIL-100(Cr) [MIL-100(Cr)/NHEtNH₂], 28 mmol (0.840 g) of paraformaldehyde, 28 mmol (2.296 g) of phosphorous acid, 2 mL of 37% HCl, and 50 mL of ethanol in a 100 mL round-bottom flask.
Reflux the mixture for 18 hours.
Filter the resulting green precipitate.
Dry the precipitate under vacuum to obtain MIL-100(Cr)/NHEtNH₂.
