Description

Key Properties & Advantages
UIO-66-NH₂’s versatility stems from its unique combination of UIO-66’s inherent strengths and amino-mediated functionality:

Inherited UIO-66 Stability: Retains the series’ signature thermal and chemical resilience—withstands temperatures up to 380°C (under inert conditions) and resists degradation in acids, bases, and organic solvents, ensuring durability in harsh operational environments.
Ordered Porous Structure: Maintains a well-defined 3D porous network with a large BET surface area (typically 750–1050 m²/g) and uniform pore size (~1.0 nm), providing abundant space for molecular adsorption and reaction.
Amino-Enhanced Surface Reactivity: The introduced -NH₂ groups deliver:
Improved Hydrophilicity: Enhances interactions with polar molecules (e.g., water, CO₂, alcohols), critical for aqueous-phase applications.
Strong Molecular Recognition: Enables selective binding with acidic or electrophilic molecules via hydrogen bonding, electrostatic interactions, or covalent coupling (e.g., Schiff base formation).
Catalytic Active Sites: Serves as a base catalyst or a platform for metal ion coordination, boosting activity in organic synthesis and CO₂ conversion.
Batch-to-Batch Consistency: KAR-F30-NH₂ ensures minimal variation in key properties (surface area, porosity, amino group density), a vital advantage for scaling from lab research to industrial processes.
Applications
CO₂ Capture & Gas Separation
Selective CO₂ Adsorption: Amino groups strongly interact with CO₂ via acid-base interactions, enabling efficient capture from flue gases, biogas, or ambient air. Its stability allows for repeated adsorption-desorption cycles, supporting energy-efficient carbon capture systems.
Gas Mixture Separation: Enhances selectivity for CO₂ over N₂, CH₄, or H₂ in mixed streams, critical for natural gas purification and hydrogen fuel processing.
Organic Catalysis
Base-Catalyzed Reactions: Amino groups act as active sites for reactions like Knoevenagel condensation, Michael addition, and transesterification, eliminating the need for toxic homogeneous bases.
Metal-Organic Catalyst Support: Coordinates with metal ions (e.g., Cu²⁺, Ni²⁺) to form stable catalytic complexes, enhancing activity in hydrogenation, oxidation, and CO₂ conversion reactions.
Heavy Metal Ion Adsorption
Water Purification: Amino groups chelate with heavy metal ions (e.g., Hg²⁺, Cd²⁺, Pb²⁺) via donor-acceptor interactions, enabling efficient removal of toxic contaminants from wastewater. Its high surface area and stability ensure reusable performance.
Drug Delivery Systems
Controlled Release Platforms: The porous structure encapsulates drug molecules, while amino groups enable pH-responsive release (triggered by acidic tumor microenvironments) and bioconjugation with targeting ligands (e.g., antibodies). Its biocompatible zirconium framework minimizes toxicity, supporting safe biomedical applications.
