Biosynthesis of Cu and CuO nanoparticles using aqueous leaves extract of <i>Sambucus nigra L.</i>

Abstract

In this research we are synthesized CuO nanoparticles (NPs) using water extract of. Also the total phenolic content of <em>Sambucusnigra </em>L. leaves water extract was measured by the Folin-Ciocalteu method. For confirmation the structure of synthesized bio-CuO-NPs we are employed X-ray Diffraction (XRD), Ultraviolet-visible (UV–vis), Fourier Transform Infrared (FTIR) spectroscopies, Scanning Electron Microscopy (SEM), and Transmission electron microscopy (TEM) methods that indicated that synthesized bio-CuO NPs have crystalline face-centered cubic (<em>fcc</em>) CuO phase with spherical morphology and with size about 14 nm. It should be mentioned that two different temperatures (100 and 400 ^o C) caused to Cu and CuO NPs respectively.
