MIL-101(Cr) Metal-Organic Framework PowderRESEARCH GRADE MATERIAL
|
||||||||||||||||||||||||
|
This material requires strict anhydrous and inert atmosphere handling to prevent moisture-induced degradation. Thermal activation under controlled conditions is necessary to restore porosity before use.
- Ambient Exposure Sensitivity: The material is highly sensitive to ambient moisture and oxygen, requiring storage in sealed containers or inert gas environments.
- Inert Gas Handling: All transfers and manipulations must be performed inside a glovebox or under a continuous flow of anhydrous inert gas.
- Thermal Activation: The material must undergo thermal treatment to remove adsorbed species and activate the pore structure prior to experimental use.
- Degradation Risk: Exposure to ambient conditions can cause phase contamination or irreversible degradation of the framework structure.
- Storage Conditions: Containers must be tightly sealed and stored in a dry, inert atmosphere away from direct light and heat sources.
How does the hierarchical pore structure of MIL-101(Cr) with window sizes of 1.2–1.6 nm and pore sizes of 2.9–3.4 nm enhance its molecular sieving and gas separation capabilities?
The dual pore system provides size-selective access for guest molecules, enabling efficient molecular sieving. The large pore cavities (2.9–3.4 nm) accommodate bulky adsorbates while the smaller windows (1.2–1.6 nm) control diffusion, as stated in the technical specifications. This architecture, combined with an ultra-high BET surface area >2500 m²/g, optimizes mass transfer and guest retention for gas storage and separation.
What chemical stability does MIL-101(Cr) offer for integration into liquid-phase catalytic or membrane applications?
MIL-101(Cr) exhibits high liquid-phase chemical stability, making it suitable for harsh validation parameters in electrocatalysis, photocatalysis, and matrix membrane fabrication. The chromium-based framework maintains structural integrity under diverse solvent conditions, as noted in the product's dual stability architecture. This robustness allows reliable performance in continuous flow or batch processes without phase contamination.
What are the critical storage and handling requirements to maintain the structural integrity of MIL-101(Cr) powder?
The product is highly sensitive to ambient exposure; containers must be kept tightly sealed or handled exclusively within an anhydrous inert gas environment to prevent phase contamination or degradation before thermal validation. This precaution is essential to preserve the ultra-high surface area and pore structure. Users should avoid moisture and oxygen exposure during transfer and storage.
MIL-101(Cr) research-grade MOF powder provides an ultra-high BET surface area exceeding 2500 m²/g with dual mesoporous windows of 1.2–1.6 nm and pore sizes of 2.9–3.4 nm, making it suitable for gas storage, separation, and catalytic workflows, though its strong ambient sensitivity demands anhydrous inert handling and tightly sealed storage.
Positive
- Ultra-high porosity: The crystalline matrix exceeds 2500 m²/g BET surface area, enhancing mass transfer and guest molecular retention for advanced sorption and separation applications.
- Dual stability architecture: The framework offers high physical, thermal, and liquid-phase chemical stability, supporting operation under harsh validation parameters.
Trade-offs
- Ambient exposure sensitivity: This material is highly sensitive to ambient exposure and must be kept in tightly sealed containers to prevent phase contamination or degradation before thermal validation.
- Inert atmosphere handling required: For safe manipulation, the powder should be handled exclusively within an anhydrous inert gas environment to avoid moisture- or air-induced degradation.
