Simple and large scale refluxing method for preparation of Ce-doped ZnO nanostructures as highly efficient photocatalyst

▸ A simple refluxing method was applied for preparation of Ce-doped ZnO nanostructures. ▸ The XRD patterns demonstrate that loading of Ce4+ ions does not change the structure of ZnO. ▸ The results indicate that the nanostructures with 0.05 mole fraction of Ce4+ ions exhibit highest photocatalytic activity. ▸ The nanostructures have highest photocatalytic activity at solutions with pH between 5.4 and 9.
