Used as a metal-organic framework (MOF) building block in gas storage and separation processes, particularly for carbon dioxide capture and hydrogen storage. Exhibits catalytic activity in oxidation reactions due to the iron center’s redox properties. Applied in water treatment systems for the removal of heavy metals and organic pollutants through adsorption and photocatalytic degradation. Investigated for use in sensors for detecting volatile organic compounds owing to its porous structure and coordination sites. Also explored in drug delivery systems where controlled release is facilitated by the biodegradable nature of the iron-carboxylate bonds.
