Preparation and Characterization of Graphene Oxide-ZnO Nanocomposites
A composite of graphene oxide supported by ZnO nanoparticles (GO-ZnO nanocomposites) was prepared through a simple chemical approach. The lamellar graphite oxide sheets in this composite were exfoliated and decorated randomly by ZnO nanoparticles with a mean size of 20 nm. In addition, the photocatalytic experiments exhibit that the GO-ZnO nanocomposites have a good photocatalytic activity on degradation of methylene blue under UV light irradiation. This method provides a facile and straightforward approach to deposit ZnO nanoparticles onto the graphene oxide sheets and may be readily extended to the preparation of other classes of hybrids based on GO sheets for technological applications.
