Abstract
Heterostructured Dye Sensitized Zeolite nanocomposites (Dye sens ZEO) were successfully prepared by an ultrasonication method. The structural analyses of the heterogeneous catalyst were confirmed using various characterization techniques such as XRD, FT-IR, SEM, UV-DRS, PL, EDX, and Mapping. From the studies of FT-IR, EDX and SEM, the good binding between dye molecule and zeolite was confirmed. The SEM studies revealed that the prepared material in cubic morphology. The Dye sens ZEO nanocomposite participated to photodegradation process of levofloxacin (LVF) drug which was examined by UV visible spectroscopy. It shows that greatest photocatalytic activity within 60 mins under visible light irradiation. The identification of degradation intermediates of LVF using GC-MS spectroscopy. The dye molecules contain azo group and zeolite consist absorption properties were very useful for the transformation of electron which were enhanced the photocatalytic activity. In scavenger studies, hydroxide radical play a superior role in the photodegradation mechanism. Finally, the photocatalyst pick up from the degraded solution using centrifugation method and used to further cycle.
