Abstract:

Four 1,3,5-tricarboxylic benzoic acid-based metal organic frameworks (BTC-MOFs) have been synthesized using Fe, Ni, Cu and Zn as metal ions and 1,3,5-tricarboxylic benzoic acid as organic linkers in aqueous medium under certain experimental conditions. The structural features of BTC-MOFs have been confirmed through morphological and spectroscopic analysis. Afterward, the comparison study has been made on water stability and absorption capacity of BTC-MOF at different temperatures (25 °C, 50 °C, 75 °C and 100 °C) using thermogravimetric analysis and UV–visible spectroscopy. Our study results confirm that Fe-BTC has high water stable structure among four BTC-MOFs due to induces dehydration process. Here, we have noted interesting order (i.e., Fe-BTC > Ni-BTC > Cu-BTC > Zn-BTC) for water stability and absorption capacity. Importantly, such type of experimental study helps to fill the major gap between laboratories to industrial research in term of forecasting biomedical application of MOFs.
