Description
Key Properties & Advantages
MOF-303 (KAR-F45)’s performance is defined by its unique structural design and aluminum-based chemistry:
Ultra-High Water Vapor Adsorption: Exhibits exceptional affinity for water molecules, enabling efficient capture of atmospheric moisture even in arid environments—critical for sustainable freshwater production.
Precision Pore Architecture: 0.3–0.5 nm pores enable molecular sieving, supporting selective adsorption of small molecules (e.g., SO₂, water) while excluding larger contaminants.
Exceptional Stability: Maintains structural integrity in harsh conditions, including:
Wide pH range (3–11) in aqueous solutions.
Thermal stability up to 400°C (inert atmosphere), suitable for high-temperature adsorption-desorption cycles.
Resistance to organic solvents, ensuring durability in industrial separation processes.
High Surface Area (≥1100 m²/g): Maximizes active sites for adsorption and catalytic reactions, enhancing efficiency in gas capture and liquid-phase separation.
Uniform Particle Size (~0.2 μm): Ensures consistent packing in industrial columns and uniform dispersion in composite materials (e.g., membranes, probes).
Core Applications
Atmospheric Water Harvesting in Arid Environments
MOF-303 (KAR-F45)’s superior water adsorption capacity makes it a game-changer for sustainable water production:
Desert Water Generation: Efficiently captures water vapor from dry air (even at low humidity, ≤30% RH), releasing pure water upon mild heating. Ideal for off-grid communities and arid regions with limited access to freshwater.
Low-Energy Cooling Systems: Functions as an adsorbent in water-based cooling cycles, reducing energy consumption compared to traditional refrigeration technologies.
Selective Gas Purification
Its precision pores and aluminum active sites enable targeted removal of toxic or unwanted gases:
SO₂ Capture in Methane/CO₂ Streams: Selectively adsorbs sulfur dioxide (SO₂) from mixed gas streams (e.g., natural gas, industrial flue gases), preventing catalyst poisoning in downstream processes. This selectivity is critical for maintaining efficiency in industrial catalytic systems.
Acid Gas Separation: Potential for CO₂ capture and purification of hydrogen streams, supporting clean energy and carbon reduction initiatives.
Advanced Liquid Separation (Pervaporation)
Modified MOF-303 (KAR-F45) excels in liquid-phase separation, particularly in industrial solvent purification:
Water-Ethanol Separation: When integrated into membranes, demonstrates enhanced performance and stability in pervaporation processes, enabling efficient dehydration of ethanol—a key step in biofuel production and pharmaceutical manufacturing.
Clinical Diagnostics & Glycoproteomics
In biomedical research, MOF-303 (KAR-F45) serves as a platform for advanced analytical tools:
Functionalized Magnetic Probes: Derivatives of KAR-F45 are used to develop high-sensitivity magnetic probes for analyzing N-linked glycopeptides. These probes enable precise detection of glycopeptides in biological samples, supporting applications in clinical diagnostics and glycoproteomics research.
