چکیده انگلیسی
The present work deals with the preparation of WO3 and WO3-ZnO nanocomposites in presence of ultrasonic irradiation, and its use in the sonocatalytic degradation of brilliant blue dye. WO3-ZnO nanocomposite is prepared using one step in-situ ultrasound assisted method. The successfully prepared WO3 and WO3-ZnO nanocomposites were characterized using different characterization techniques such as XRD, Raman, BET, FE-SEM and EDS. The XRD pattern reveals that the formation of monoclinic and hexagonal crystal structures of WO3 and ZnO respectively. BET study shows that WO3-ZnO nanocomposite have maximum surface area than that of the WO3. EDS study confirms the formation of WO3-ZnO nanocomposites. Further the use of the prepared WO3 and WO3-ZnO nanocomposites as a sonocatalyst for the degradation of brilliant blue dye. The rate constant (k) was evaluated as a function of the initial concentration of brilliant blue dye. It is found that WO3-ZnO nanocomposites exhibits maximum sonocatalytic activity as compared to WO3 photocatalyst.
