|
MIL-101(Al) is highly sensitive to ambient moisture and oxygen, requiring storage in sealed containers under anhydrous inert gas to prevent phase contamination or degradation. The material must be handled exclusively in an inert environment prior to thermal validation to maintain structural integrity.
- Ambient Sensitivity: Exposure to ambient atmosphere causes phase contamination or degradation of the MIL-101(Al) crystal structure.
- Sealed Container Requirement: Containers must be kept tightly sealed at all times to prevent moisture and oxygen ingress.
- Inert Gas Handling: All handling operations must be performed exclusively within an anhydrous inert gas environment, such as a glovebox.
What is the effective pore size range of MIL-101(Al) and how does it enable molecular size-exclusion separations?
MIL-101(Al) features precision microporous channels with a pore size of 0.4–0.6 nm, as stated in the technical specifications. This tight sub-nanometer definition allows sharp molecular size-exclusion and high-selectivity trapping, making it suitable for gas purification and carbon capture validation where small molecule discrimination is critical.
Can MIL-101(Al) powder be integrated into mixed-matrix membranes without compromising its structural integrity?
Yes, the material's controlled nanoscale particle distribution (100–1000 nm) ensures uniform phase configuration and high integration metrics within mixed-matrix separation membranes. The homogeneous dispersion promotes consistent pore accessibility and avoids aggregation, preserving the framework's high surface area and selectivity in composite devices.
What handling and storage conditions are required to prevent degradation of MIL-101(Al) before use?
MIL-101(Al) is highly sensitive to ambient exposure, so containers must be kept tightly sealed or handled exclusively within an anhydrous inert gas environment. This prevents phase contamination or degradation before thermal validation, as noted in the logistics notice. Storage under dry, inert conditions is essential to maintain the material's porosity and crystallinity.
MIL-101(Al) is an aluminum-based MOF powder with BET surface area >1000 m²/g and precision microporous channels (0.4–0.6 nm) for selective gas capture and separation, but requires strict anhydrous inert gas handling to prevent ambient degradation.
Positive
- High Specific Surface Area >1000 m²/g: The optimized internal micro-architecture yields a surface area exceeding 1000 m²/g, enabling targeted gas molecule retention for selective capture applications.
- Precision Microporous Channels (0.4–0.6 nm): Tight pore definition within 0.4–0.6 nm enables sharp molecular size-exclusion and high-selectivity trapping, critical for gas separations.
Trade-offs
- Ambient Exposure Sensitivity: The material is highly sensitive to ambient exposure; containers must be tightly sealed or handled exclusively within an anhydrous inert gas environment to prevent phase contamination or degradation.
