MOF-74(Co) is widely used in gas storage and separation due to its high density of open metal sites and strong affinity for small gas molecules. It exhibits exceptional capacity for carbon dioxide and methane adsorption, making it a promising material for carbon capture and natural gas storage applications. Its uniform pore structure and thermal stability allow for efficient and selective gas uptake, even under low-pressure conditions. Additionally, MOF-74(Co) has been explored in catalysis, where the cobalt centers act as active sites for oxidation reactions and electrochemical processes such as CO2 reduction. Its performance in sensing and ion exchange has also been investigated, particularly in environmental monitoring and purification technologies.
