Description
ZIF-8 (KAR-F01) Technical Datasheet
Key Properties & Advantages
ZIF-8 (KAR-F01)’s performance stems from its robust structure and optimized synthesis:
-
Uniform Microporous Structure: Features a well-defined pore network with a pore size of ~3.4Å—ideal for molecular sieving of small molecules (e.g., CO₂, N₂, H₂). Its high BET surface area (typically 1400–1900 m²/g) provides abundant adsorption sites, enhancing efficiency in separation and catalysis.
-
Exceptional Stability: Inherits ZIF-8’s legendary chemical resilience, stable in water (pH 4–12), organic solvents, and moderate temperatures (up to 250°C under inert conditions). Outperforms many MOFs in humid or aqueous environments, a critical advantage for industrial use.
-
Optimized Ball-Milling Synthesis: Our proprietary synthesis method ensures:
-
Preserved Crystallinity: Maintains the ordered structure of ZIF-8, avoiding amorphization common in conventional grinding processes.
-
Efficient Mass Production: Scalable synthesis without compromising quality, making industrial-scale deployment feasible.
-
Controlled Particle Size: Adjustable D50 (1–5μm) via synthesis tuning, allowing customization for specific applications (e.g., fine powders for catalysis, larger particles for packed-bed separators).
-
-
Biocompatibility: Zinc-based composition and inert framework make it suitable for biocompatible applications, such as drug delivery carriers.
Core Applications
CO₂/N₂ Selective Adsorption
ZIF-8 (KAR-F01) is a benchmark material for CO₂ separation, leveraging its ~3.4Å pores and zinc-mediated interactions:
-
Selectively adsorbs CO₂ (kinetic diameter ~3.3Å) over N₂ (~3.6Å) via molecular sieving, making it ideal for carbon capture from flue gases, biogas upgrading, and air separation.
-
High CO₂ adsorption capacity (up to 4.5 mmol/g at 273K, 1 bar) and reversible adsorption-desorption cycles enable energy-efficient separation processes.
Molecular Sieving
Its precise pore size enables selective separation of small molecules in industrial and research settings:
-
Sieves light hydrocarbons (e.g., C₂H₆/C₂H₄, CH₄/N₂) for petrochemical purification.
-
Purifies gases like H₂ (kinetic diameter ~2.9Å) from mixed streams, supporting hydrogen fuel production.
Biocompatible Drug Carriers
ZIF-8 (KAR-F01)’s biocompatibility and porous structure make it an excellent drug delivery platform:
-
Encapsulates small-molecule drugs within its pores, protecting them from degradation.
-
Enables controlled release via pH-triggered framework dissolution (e.g., in acidic tumor microenvironments), improving therapeutic efficacy and reducing side effects.
Industrial Catalysis
Serves as a stable catalyst support or intrinsic catalyst for various reactions:
-
Hosts metal nanoparticles (e.g., Pd, Pt) for hydrogenation, oxidation, or coupling reactions, with its pores confining reactants to enhance selectivity.
-
Zinc ions act as mild Lewis acid sites, promoting catalytic activity in organic synthesis (e.g., esterification, cycloadditions).
