Abstract:
: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.
