Structural, Optical and Photocatalytic Studies on Pure and Transition metal ion Doped ZnO-Graphene Nanocomposites

摘要

This work reports the structural, optical and photocatalytic properties of nanocomposites made with graphene and transition metal ion doped ZnO, the graphene-ZnO nanocomposite. The doped and the un-doped ZnO were prepared by chemical method and then the nanocomposites were made. Structural confirmation was done by XRD and Raman spectroscopy. Optical properties were studied by UV-Vis and PL spectroscopies. Photocatalytic activity on the degradation of an industrial dye was studied. It was observed that the nanocomposite with transition metal ion doped ZnO have a higher degradation efficiency compared to the same with un-doped ZnO.
