UIO-66-(OH)₂ (KAR-F30-(OH)₂) Technical Datasheet

Key Properties & Advantages

UIO-66-(OH)₂’s performance is driven by its structural design and hydroxyl functionalization:

Exceptional Thermal & Chemical Stability: Maintains structural integrity at temperatures up to 380°C (under inert conditions) and resists degradation in acidic, basic, and organic solvent environments—ideal for harsh operational settings where many MOFs fail.
Ordered Porous Structure: Features a well-defined 3D porous network with a large BET surface area (typically 750–1100 m²/g) and uniform pore size (~1.0 nm), enabling efficient molecular diffusion and high adsorption capacity.
Hydroxyl-Enhanced Surface Reactivity: The -OH groups introduce:
- Strong hydrogen-bonding capabilities, improving selectivity for polar molecules (e.g., CO₂, water, alcohols).
- Lewis acid/base sites, enabling participation in acid-catalyzed or base-catalyzed reactions.
- Chelation with metal ions, facilitating functionalization for targeted catalysis or sensing.
Tailored Selectivity: The density of hydroxyl groups can be controlled during synthesis, allowing customization of interactions with target molecules (e.g., adjusting affinity for specific gases or pollutants).
Batch-to-Batch Consistency: KAR-F30-(OH)₂ ensures minimal variation in key properties (surface area, porosity, functional group density), a critical advantage for scaling from lab research to industrial applications.

Applications

Gas Storage & Separation

Selective Gas Adsorption: Hydroxyl groups enhance affinity for polar gases like CO₂ and H₂, making it effective for:

Carbon capture from flue gases or industrial emissions (via selective CO₂ adsorption).
Hydrogen purification and storage (supporting clean energy technologies).
Mixed gas separation (e.g., CO₂/CH₄ in natural gas upgrading, H₂/CO₂ in syngas processing).

Liquid-Phase Adsorption

Pollutant Removal: Its porous structure and hydroxyl-mediated interactions enable efficient adsorption of liquid-phase contaminants, including:

Organic pollutants (e.g., phenols, dyes, pharmaceuticals) via hydrogen bonding and hydrophobic interactions.
Heavy metal ions (e.g., Cr³⁺, Cu²⁺) through chelation with -OH groups, supporting wastewater purification.

Catalytic Applications

Acid/Base Catalysis: Hydroxyl groups act as active sites for acid-catalyzed reactions (e.g., esterification, dehydration) and base-mediated processes (e.g., aldol condensation), leveraging their amphoteric nature.
Catalyst Support: Serves as a stable platform for anchoring metal nanoparticles (e.g., Pt, Ru) or metal oxides, with -OH groups enhancing particle dispersion and catalytic activity in reactions like:
- CO₂ hydrogenation to value-added chemicals (e.g., methanol).
- Oxidation of organic compounds (e.g., alcohol oxidation to aldehydes).
