Modification of MOFs (type MOF-74) to improve CO₂ adsorption, selectivity and moisture stability - 2024/2027

This study focuses on the modification of metal-organic frameworks of the MOF-74 type to optimize their performance in CO₂ capture, a key component in climate change mitigation strategies. MOF-74 materials are known for their high porosity and strong affinity for CO₂, but they face limitations in humid environments and in selectivity against other gases. By modifying the linkers or metal centers, the aim is to enhance adsorption capacity, increase selectivity toward CO₂ over N₂ or H₂O, and reinforce structural stability under real-world conditions. These improvements are essential for practical applications in gas separation and purification of industrial streams.

The work combines synthesis, characterization, and adsorption testing to evaluate the impact of these modifications. By developing more robust and selective MOFs, the project contributes to more efficient and sustainable carbon capture technologies. This positions modified MOFs as promising materials in the context of industrial decarbonization.
