【 摘 要 】

Graphene spheres decorated with CuO nanoflowers were successfully synthesized via a spray-drying method. Scanning-electron and transmission-electron microscopy were used to confirm that the graphene formed spherical structures and that the CuO nanoflowers were well dispersed on the surface of these graphene spheres. These novel nanocomposites had an enhanced photocatalytic performance, achieving a 95.2% decomposition of methyl orange after 15 min in the presence of H2O2 when irradiated by visible light. These nanocomposites performed much better than CuO powders alone.
