Description
Key Properties & Advantages
UIO-66-F4’s unique performance stems from its fluorinated structure and retention of UIO-66’s core strengths:
Tetrafluoro-Modified Hydrophobicity: The introduction of four fluorine atoms per ligand creates a highly hydrophobic surface, minimizing water adsorption and enhancing selectivity for non-polar or weakly polar molecules—ideal for applications in humid or aqueous environments.
Enhanced Chemical & Environmental Stability: Outperforms many MOFs in acidic conditions (pH ≥ 2) and humid atmospheres, maintaining structural integrity where non-fluorinated UIO-66 derivatives may degrade. It also resists oxidation and halogenation, ensuring longevity in reactive environments.
Inherited High Porosity: Retains a well-ordered porous network with a large BET surface area (typically 650–950 m²/g) and uniform pore size (~1.0 nm), providing ample space for molecular adsorption and sieving.
Chemical Inertness: The fluorinated framework exhibits low reactivity with polar solvents, acids, and oxidizing agents, making it suitable for applications involving aggressive chemical environments.
Batch-to-Batch Consistency: KAR-F30-F4 undergoes stringent quality checks to ensure minimal variation in key properties (porosity, hydrophobicity, stability), a critical advantage for scaling from lab research to industrial processes.
Applications
Gas Separation
Selective Gas Adsorption: Its hydrophobicity and tuned pore size enable exceptional performance in separating non-polar/polar gas mixtures, including:
CO₂/N₂ Separation: Efficiently distinguishes between CO₂ and N₂ in flue gases or air, supporting carbon capture in humid industrial environments (where water interference is a challenge for hydrophilic MOFs).
Hydrocarbon Separation: Selectively adsorbs light hydrocarbons (e.g., CH₄, C₂H₆) from gas streams, aiding in natural gas purification and fuel processing.
Organic Catalysis
Fluorine-Related Reactions: The tetrafluoro groups serve as both structural modifiers and catalytic promoters, enhancing activity and selectivity in:
Fluorination reactions (e.g., electrophilic fluorination of aromatics).
Halogen exchange reactions (leveraging fluorine’s high electronegativity).
Hydrophobic-mediated catalysis (e.g., esterification or alkylation in aqueous-organic biphasic systems, where its hydrophobicity concentrates organic substrates at the active site).
Specialized Molecular Sieving
Size- and Hydrophobicity-Driven Separation: Its uniform pore size and hydrophobic surface enable precise sieving of molecules based on both size and polarity, making it valuable for:
Purification of fluorinated compounds (e.g., pharmaceutical intermediates).
Removal of non-polar contaminants from aqueous streams (e.g., oil-soluble pollutants).
Separation of isomers with subtle polarity differences (e.g., fluorinated aromatic isomers).
