The mixed Cu and Zn oxide (Cu/ZnO) nanoparticles have been synthesized using Brassica juncea L. plants. The synthesized Cu/ZnO nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy dispersive spectrum (EDS). It was found that the synthesized Cu/ZnO nanoparticles were corresponding to the Cu(0.05)Zn(0.95)O structure. The shapes of the synthesized ZnO nanoparticles were nonuniform, but the CuO nanoparticles showed a spherical shape. The CuO nanoparticles entered in the structures of ZnO nanoparticles. An average size of 97 nm was obtained for Cu(0.05)Zn(0.95)O. The Cu(0.05)Zn(0.95)O nanoparticles were pure. The method for synthesis of Cu(0.05)Zn(0.95)O nanoparticles using Cu hyperaccumulator (B. juncea) plants constitutes a new insight into the recycling of hyperaccumulator and provides a novel route for further development of green nanostructure syntheses.
利用芸薹属植物（Brassica juncea L.）合成了混和的铜锌氧化物（Cu/ZnO）纳米粒子。通过 X 射线衍射（XRD）、透射电子显微镜（TEM）和能量色散谱（EDS）对合成的 Cu/ZnO 纳米粒子进行了表征。结果表明，合成的 Cu/ZnO 纳米粒子与 Cu(0.05)Zn(0.95)O 结构相对应。合成的 ZnO 纳米粒子的形状不均匀，但 CuO 纳米粒子呈球形。CuO 纳米粒子进入了 ZnO 纳米粒子的结构中。Cu(0.05)Zn(0.95)O 的平均粒径为 97nm。Cu(0.05)Zn(0.95)O 纳米粒子是纯净的。利用铜超富集植物（芸薹属植物）合成 Cu(0.05)Zn(0.95)O 纳米粒子的方法为超富集植物的回收提供了新的思路，并为进一步发展绿色纳米结构合成提供了新途径。
