Description

Key Properties & Advantages
UIO-66-(OH)???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?C1100 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., CO?, 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)? 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 CO? and H?, making it effective for:
Carbon capture from flue gases or industrial emissions (via selective CO? adsorption).
Hydrogen purification and storage (supporting clean energy technologies).
Mixed gas separation (e.g., CO?/CH? in natural gas upgrading, H?/CO? 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:
CO? hydrogenation to value-added chemicals (e.g., methanol).
Oxidation of organic compounds (e.g., alcohol oxidation to aldehydes).
