| Abstract: |
| Metal-organic frameworks (MOFs) have been attracted considerable attention for their applications in gas storage/separation, adsorption as well as catalysis. In other hand, the photocatalytic decolorization of methylene blue dye in aqueous solution using a novel photocatalyst based on metal–organic frameworks was investigated under UV light. In this study, for the first time, a facile ultrasonic method was employed to prepare Iron based metal organic framework (Fe-benzenetricarboxylic (FeBTC)) under atmospheric pressure as photocatalyst. The as-obtained materials were characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and photoluminescence (PL) spectroscopy. Effect of ultrasound irradiation temperature (50 and 70 oC) and reaction time (90 and 120 min) on photocatalytic degradation of Methylene Blue were investigated. In the images of FESEM observed that nanoparticles size of samples prepared at 70 oC are smaller. And also Photoluminescent analysis has shown that electron-hole recombination of sample prepared at 90 minutes is higher. The results indicated that increase of ultrasound irradiation temperature decreased the nanoparticles size and the sample prepared at higher time exhibited the highest photocatalytic activity among the screened samples. The successful synthesis of the MOFs herein highlights the possibilities of producing other MOFs conveniently and efficiently via this method. Therefore, it is reasonable to believe that MOFs photocatalysts have great potentiality in environmental remediation. |
