In this procedure, the fabrication process of IRMOF-3 follows the methodology reported in our previous work. Specifically, 932 mg Zn(NO3)2•6H2O was dissolved in 100 ml DMF under magnetic stirring at room temperature to create a homogeneous solution. Subsequently, 181 mg 2-aminoterphthalic acid was added to the above mixture and subjected to ultrasonication for several minutes at room temperature until a clear solution formed. The resulting homogeneous solution was then placed in a Teflon-lined stainless-steel autoclave and allowed to react at 100 ºC for 24 h. Upon cooling to room temperature, the powder was collected by centrifugation, and washed multiple times with DMF and ethanol to eliminate any organic and inorganic residues.
