摘要：

We reported a simple and convenient approach for the synthesis of high-yield ZnO/Ag nanocomposites by applying one-pot nonaqueous route. The products were characterized by X-ray diffraction, transmission electron microscopy, UV-vis spectroscopy and photoluminescence spectroscopy. The results showed that the products consisted of metallic Ag and ZnO components; Ag nanoparticles were attached to the ZnO nanorod cores; ZnO/Ag hybrid nanoarchitectures displayed tunable optical properties. Moreover, these ZnO/Ag heterostructured nanoassemblies possessed enhanced visible-light photocatalytic activity based on the unique ZnO-Ag interphase boundaries and synergetic effect between neighboring Ag nanoparticles and ZnO nanorods.
