India A facile synthesis of Graphene oxide-copper oxide nanocomposite (GO-CuO) was performed by using a wet chemical method by using graphene oxide and copper acetate precursors. There is no any other polymer or seed involved for preparation of nanocomposite The as-synthesized materials structure and morphology was calibrated by Powdered X-ray diffraction (P-XRD), and intercalated with Raman spectroscopy. Morphology features of GO-CuO nanocomposites were explored by FE-SEM, the quantitative and elemental analyses of as-synthesized materials were measured by electron dispersive spectroscopy (EDS), the size, shape, and orientation of as-synthesized catalysts were examined by transmission electron microscopy TEM with selective area electron diffraction. The results reveal that the nanocomposite with a size range from 5-10 nm uniformly anchored onto GO sheets and photocatalytic degradation of lead ion was studied by using a UV-VIS spectrophotometer. Significant high-performance photocatalytic activity of GO-CuO nanocomposite was exhibited on lead ions degradation under solar light. http://pubs.sciepub.com/aees/7/5/3/aees-7-5-3.pdf Reduced graphene GO-CuO nanocomposite TEM photocatalytic degradation
