CO₂ Adsorption
One of the most widely studied applications of MOF-74(Mg) is its use in CO₂ adsorption. The material exhibits excellent CO₂ uptake, particularly at low pressures, due to the strong interaction between CO₂ molecules and the open magnesium sites. This property makes MOF-74(Mg) a promising candidate for CO₂ capture and storage (CCS) technologies.
Water Adsorption
In addition to CO₂ adsorption, MOF-74(Mg) has been investigated for its potential in water adsorption. The material exhibits a decent water uptake of 25.172 g/g at 1 bar, making it a promising candidate for atmospheric water harvesting (AWH). The adsorption process is influenced by the interaction between water molecules and the open metal sites, as well as the pore structure of the framework.
Electrochemical Applications
MOF-74(Mg) has also been explored for its potential in electrochemical applications, particularly in solid-state electrolytes and batteries. The material's high ionic conductivity and stability make it an attractive candidate for use in all-solid-state sodium metal batteries (ASSMBs). When used as a solid electrolyte, MOF-74(Mg) exhibits an ionic conductivity of 8.53 × 10⁻⁴ S cm⁻¹ at 70 °C, along with a wide potential window of 1-4.3 V.
Hydrogen Storage
Hydrogen storage is another promising application of MOF-74(Mg). The material's open metal sites and porous structure enable strong interactions with hydrogen molecules, making it suitable for high-capacity hydrogen storage. When modified with defective frameworks and catalysts such as platinum (Pt), MOF-74(Mg) can achieve a reversible hydrogen storage capacity of 2.55 wt.% at 160 °C and 81 bar. This performance is further enhanced by the material's rapid hydrogen uptake/release and stable cycling capabilities.
