Synthesis and Characterization of Fe-Based Metal-Organic Frameworks:MIL53 (Fe) for Methylene Blue Degradation

In recent years, volume of waste water produced by diverse field of industries is one the most vital challenges. To tackle this issue, numerous solutions have been submitted and among them, utilizing Metal- Organic Frameworks (MOFs) has been considerably paid attention as an appropriate option for water treatment due to their unique properties, such as low band gap and high specific surface area. In this study, MIL53 (Fe) was synthesized using nitrite salt source (FeNO3.9H2O) via solvo-thermal method at 120ºC, 150ºC and 180ºC. Subsequently, obtained powders was characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and UV-vis DRS. Eventually, photocatalytic efficiency of prepared samples was analyzed via Methylene Blue (MB) degradation under halogen lamp (500 W). Obtained results showed that the synthesized powder at 180ºC (sample C) had the most percentage of crystallinity and light absorption. Likewise sample (C) was the most efficient sample and possessed the highest band gap and the most rate of dye degradation.
