Description

Key Properties & Advantages
ZIF-67’s versatility stems from its cobalt-centered structure and zeolitic framework:

Cobalt-Driven Activity: Cobalt nodes provide Lewis acid sites and redox activity, enhancing catalytic performance in reduction/oxidation reactions and enabling electroactive behavior in energy devices.
High Porosity & Surface Area: Features a well-defined porous network with a large BET surface area (typically 1200–1600 m²/g) and uniform pore size (~1.1 nm), facilitating efficient molecular diffusion, adsorption, and catalytic site accessibility.
Exceptional Chemical Stability: Exhibits robust stability in aqueous and organic environments (pH 3–11) and moderate thermal resistance (up to 300°C under inert conditions), outperforming many MOFs in practical operational settings.
Processability: Easily fabricated into powders, thin films, or composites with other materials (e.g., cement, polymers, substrates), expanding its applicability across industries.
Tunable Functionality: Retains structural integrity during post-synthetic modification (e.g., metal doping, ligand functionalization), allowing customization for target applications.
Core Applications
Biosensing & Disease Diagnosis
ZIF-67’s high surface area and cobalt-mediated catalytic activity make it an ideal component in composite materials for biosensing:

Enhances catalytic and electrocatalytic signals in biosensors, enabling sensitive detection of biomolecules (e.g., biomarkers, pathogens) via amplified electrochemical or optical responses.
Its porous structure can encapsulate recognition elements (e.g., antibodies, enzymes), improving specificity in diagnostic assays.
Cement Composites
When incorporated into cement composites, ZIF-67 delivers significant performance enhancements:

Improves compressive strength by reinforcing the cement matrix and reducing porosity through controlled particle dispersion.
Refines microstructure by facilitating more uniform hydration of cement particles, enhancing durability and resistance to cracking.
NOₓ Selective Reduction Catalysis
ZIF-67 excels as a catalyst for NOₓ (nitrogen oxide) reduction, a critical process in environmental pollution control:

Exhibits high activity for selective catalytic reduction (SCR) of NOₓ using CO as a reducing agent, even under oxygen-rich conditions (mimicking industrial flue gas environments).
Cobalt nodes act as active sites for NOₓ adsorption and activation, promoting efficient conversion to N₂ and CO₂.
Photocatalytic CO₂ Reduction
In sustainable energy research, ZIF-67 is a promising material for photocatalytic CO₂ conversion:

Demonstrates exceptional performance in reducing CO₂ to CO under light irradiation, with high CO production yields attributed to cobalt’s redox activity and the framework’s ability to concentrate CO₂ molecules.
Its porous structure enhances light absorption and charge separation, overcoming common limitations of low efficiency in photocatalytic systems.
Supercapacitor Thin Films
ZIF-67 thin films, fabricated on various substrates (e.g., carbon cloth, metal foils), are ideal for supercapacitor applications:

Display robust electrochemical performance, including high specific capacitance, excellent cycling stability (≥10,000 cycles), and rapid charge-discharge rates.
The cobalt-based framework enables pseudocapacitive behavior, complementing the electric double-layer capacitance of porous carbon substrates for enhanced energy storage.
