Description

Key Properties & Advantages
UIO-66-(COOH)???s performance is defined by its structural design and functional groups:

Exceptional Thermal & Chemical Stability: Maintains structural integrity at temperatures up to 400??C (under inert conditions) and resists degradation in acidic, basic, and organic solvent environments??outperforming many MOFs in harsh operational settings.
Highly Porous Structure: Features a well-defined porous network with a large BET surface area (typically 800?C1200 m2/g) and uniform pore size (~1.1 nm), enabling efficient molecular adsorption and diffusion.
Carboxyl-Functionalized Surface: The presence of -COOH groups enhances hydrophilicity and provides active sites for:
Coordination with metal ions (useful for catalytic functionalization).
Hydrogen bonding with polar molecules (improving selectivity in adsorption/separation).
Covalent coupling with biomolecules (critical for drug delivery applications).
Tunable Surface Properties: The density of carboxyl groups can be adjusted during synthesis to tailor interactions with target molecules, offering flexibility for custom applications.
Consistent Commercial Grade Quality: KAR-F30-(COOH)? ensures reliable performance with minimized batch variation, a key advantage for scaling from lab research to industrial use.
Applications
Gas Storage & Separation
Selective Gas Adsorption: The carboxyl groups enhance affinity for polar gases such as CO?, making it effective for carbon capture from flue gases or biogas upgrading. Its porosity also enables storage of small molecules like H? and CH?, supporting clean energy applications.
Hydrophilic Separation Processes: Outperforms non-functionalized MOFs in separating polar/non-polar gas mixtures or aqueous volatile compounds, thanks to -COOH-mediated interactions.
Catalysis
Catalytic Support & Active Site: Carboxyl groups act as anchors for metal nanoparticles (e.g., Pd, Pt) or metal ions, stabilizing catalytic centers for reactions like:
CO? hydrogenation to value-added chemicals.
Oxidation of organic pollutants.
Acid-catalyzed reactions (leveraging the weakly acidic nature of -COOH groups).
Controlled Drug Release
Biocompatible Delivery Platform: The porous structure allows encapsulation of drug molecules, while carboxyl groups enable pH-responsive release (acidic environments, e.g., tumor microenvironments, trigger drug dissociation). Its zirconium-based composition adds biocompatibility, reducing toxicity concerns.
Environmental Remediation
Heavy Metal Ion Removal: Carboxyl groups chelate with heavy metals (e.g., Pb2?, Cd2?, Hg2?) in wastewater, enabling efficient adsorption and purification of contaminated water sources.
Material Science Research
Model System for Functional MOFs: Serves as a benchmark for studying the impact of surface functional groups on MOF properties, aiding in the design of next-generation functionalized porous materials.
