Description

Key Properties & Advantages
UiO-66??s enduring utility stems from its intrinsic structural strengths and modifiable framework:

Exceptional Stability: Outperforms most MOFs in chemical and thermal resilience??withstands temperatures up to 400??C (under inert conditions), resists degradation in acids (pH ?? 2), bases (pH ?? 12), and organic solvents, and maintains integrity in aqueous environments. This stability ensures longevity in practical applications where other MOFs fail.
Tunable Framework: Its flexible structure supports diverse modification strategies:
Doping: Incorporation of metal ions (e.g., Fe, Cu, Ti) into zirconium clusters to introduce catalytic or photocatalytic activity.
Post-Synthetic Modification: Functional groups (e.g., -NH?, -OH, -COOH) can be grafted onto ligands to enhance selectivity in adsorption, coordination, or biocompatibility.
Pore Engineering: Adjustment of ligand length or linker chemistry to tailor pore size (typically 0.8?C1.2 nm) and surface area (BET 1000?C1500 m2/g) for target molecules.
High Coordination Capability: Zirconium clusters offer abundant coordination sites, enabling strong interactions with guest molecules, metal nanoparticles, or biomolecules??critical for catalysis, sensing, and drug delivery.
Structural Integrity: Retains its ordered porous network even after modification, ensuring consistent performance in applications requiring mass transport (e.g., adsorption, catalysis).
Modification Strategies
UiO-66??s tunability is enabled by its adaptable framework, supporting precise customization:

Doping: Introduction of heteroatoms (e.g., Hf, Ce) or metal ions (e.g., Ru, Co) into the zirconium clusters to modify electronic properties, enhance catalytic activity, or enable photocatalytic responses (e.g., light-driven water splitting).
Post-Synthetic Modification (PSM): Chemical functionalization of ligands after synthesis, such as:
Grafting amine (-NH?), hydroxyl (-OH), or carboxyl (-COOH) groups to improve hydrophilicity or selectivity for polar molecules.
Covalent linking of biomolecules (e.g., peptides, antibodies) for targeted biomedical applications.
Ligand Exchange: Partial or full replacement of terephthalate ligands with functionalized linkers (e.g., fluorinated, sulfonated) to adjust porosity, surface chemistry, or reactivity.
Applications Across Fields
Catalysis & Photocatalysis
Heterogeneous Catalysis: Serves as a stable support for metal nanoparticles (e.g., Pd, Pt) or as an intrinsic catalyst via zirconium??s Lewis acidity, enabling reactions like hydrogenation, oxidation, and CO? conversion.
Photocatalysis: Modified UiO-66 (e.g., with Ti doping or dye sensitization) drives light-induced reactions such as water splitting for H? production, pollutant degradation, and CO? photoreduction to fuels.
Adsorption & Separation
Gas Separation: Tuned pores and functional groups enable selective adsorption of gases (e.g., CO?/N?, H?/CH?), supporting carbon capture, natural gas purification, and hydrogen storage.
Liquid-Phase Adsorption: Removes pollutants (e.g., heavy metals, dyes, pharmaceuticals) from water via ligand-metal interactions or hydrophobic/hydrophilic effects, depending on modifications.
Sensing
Molecular Sensing: Functionalized UiO-66 (e.g., with fluorescent groups or metal ions) detects target analytes (e.g., heavy metals, volatile organic compounds, biomolecules) via changes in luminescence, conductivity, or adsorption behavior.
Environmental Sensing: Its stability in aqueous media makes it suitable for real-time monitoring of water or air quality.
Biomedical Applications
Drug Delivery: Biocompatible zirconium framework and porous structure enable controlled encapsulation and release of drugs, with modifications (e.g., -NH? groups) enhancing targeting to specific tissues.
Imaging: Doped UiO-66 (e.g., with rare-earth ions) acts as a contrast agent for magnetic resonance imaging (MRI) or fluorescence imaging, leveraging its stability in biological environments.
