Description

Key Properties & Advantages
UIO-66-(COOH)₂’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 800–1200 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)₂ 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 CO₂, making it effective for carbon capture from flue gases or biogas upgrading. Its porosity also enables storage of small molecules like H₂ and CH₄, 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:
CO₂ 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.
