Under the backdrop of advancing carbon neutrality and sustainable development goals, high-efficiency adsorption and separation materials have become a research hotspot in fields such as energy, environment, and healthcare. Metal-organic frameworks (MOFs), owing to their advantages of tunable structures, high porosity, large specific surface area, and ease of surface functional modification, have garnered widespread attention from both academia and industry. Based on the latest product data, we have systematically reviewed and recommend the following outstanding MOF materials, providing reliable material solutions for different application scenarios.
MOF-74 Series: Gas Capture and Sustained-Release Carriers with Polymetallic Centers
The MOF-74 series is a class of high-efficiency adsorbents featuring one-dimensional channels and open metal sites. The adsorption properties and stability of these materials can be tuned by varying the metal centers.

MOF-74(Mg)-1 / MOF-74(Mg)-2 (CAS: 1565828-96-7)
Both are magnesium-based MOF-74 materials, exhibiting excellent carbon dioxide and methane adsorption performance. They are suitable for applications such as carbon capture and natural gas storage. Their nanoscale particle morphology and ultra-high specific surface area further enhance gas diffusion and adsorption kinetics. Additionally, these materials demonstrate good water uptake under moderate humidity, making them applicable for atmospheric water harvesting. Their controllable degradation behavior in aqueous environments also positions them as candidate materials for sustained-release drug carriers, suitable for targeted drug delivery systems. -
MOF-74(Co) (CAS: 871658-67-2)
Cobalt-based MOF-74 maintains high gas adsorption capacity while offering good structural stability, making it particularly suitable for gas separation processes in oxygen-containing or humid environments. The open metal sites on its pore surfaces can selectively bind polar molecules such as CO₂, showing potential application value in flue gas capture. -
MOF-74(Ni) (CAS: 882977-00-6)
Nickel-based MOF-74 is one of the few MOF materials that have undergone industrial pilot-scale testing. It exhibits outstanding methane adsorption performance and can be used in vehicular or stationary natural gas storage systems. This material also possesses good water harvesting capability and drug-loading potential, demonstrating the flexibility of MOF materials for cross-domain applications spanning energy, environment, and biomedicine.

CaCl₂@MOF-808: A High-Performance Composite Atmospheric Water Harvesting Material
MOF-808 is a stable MOF featuring zirconium as the metal node and trimesic acid as the ligand. The composite material CaCl₂@MOF-808, formed by loading calcium chloride into MOF-808, demonstrates exceptional performance in the field of atmospheric water harvesting.
• Outstanding Water Harvesting Performance: This material efficiently adsorbs water vapor even under low-humidity conditions (relative humidity 20%~40%). Its actual water harvesting capacity surpasses that of commonly used benchmark materials such as MOF-303 and MOF-801, making it particularly suitable for atmospheric water harvesting in arid or semi-arid regions.
• Exceptional Stability: The zirconium-based framework provides excellent hydrothermal and chemical stability, enabling long-term use in humid, weakly acidic, or weakly alkaline environments. This significantly extends the material's lifespan and reduces system maintenance costs.
• Multifunctional Integration: Beyond water harvesting, this material also exhibits excellent adsorption capacity for gases (e.g., CO₂, CH₄) and can catalyze the decomposition of hydrogen peroxide to produce oxygen. Its surface is rich in Zr-OH sites, which are readily available for post-synthetic modification, further expanding its potential applications in catalysis, sensing, drug delivery, and other fields.
• Practical Application Scenarios: Atmospheric water harvesting devices based on CaCl₂@MOF-808 can utilize diurnal temperature variations or solar energy for operation. They adsorb moisture from the air at night and desorb it to produce pure water during the day. This provides a sustainable technological pathway to address drinking water challenges in water-scarce environments such as arid coastal areas and deserts.
With continuous optimization of synthesis processes and decreasing costs, MOF materials are transitioning from the laboratory to large-scale applications. J&K Scientific welcomes in-depth exchanges with industry peers to jointly advance the practical applications of MOF materials in green chemical engineering, clean energy, and environmental protection.
