报道了一种简便的非水一锅法合成ZnO/Ag纳米复合材料的方法。采用X射线衍射、透射电子显微镜、紫外-可见光谱和光致发光光谱对产物进行了表征。结果表明，产物由金属Ag和ZnO组成，Ag纳米粒子附着在ZnO纳米棒核上，ZnO/Ag杂化纳米结构显示出可调的光学性质。此外，ZnO/Ag异质结构纳米组装体由于其独特的ZnO-Ag界面以及相邻Ag纳米颗粒与ZnO纳米棒之间的协同效应，具有更强的可见光催化活性。
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.
