Structural and morphological analysis of ZnO-CuO/GOr nanostructures synthesized by the green chemistry route
Abstract
In this work, zinc oxide nanostructures with copper oxide supported on reduced graphene oxide (ZnO-CuO/GOr) were synthesized at different concentrations by a green chemistry route using citric acid as solvent and aqueous extract of eucalyptus as a reductant. The ZnO-CuO/GOr nanostructures obtained were morphologically analyzed with scanning electron microscopy (SEM), structurally with the X-ray diffraction (XRD) technique, and additionally, a structural chemical analysis was performed by infrared spectroscopy with Fourier transform (IR-FT). The surface morphology of the nanocomposite ZnO-CuO/GOr shows irregular agglomerations arranged uniformly on the surface of graphene oxide sheets. XRD results indicate that ZnO nanoparticles exhibit the structure of wurtzsite, CuO nanoparticles show a monoclinic phase structure. With the IR-TF spectra, biomolecules of -OH, -CH3 and C = O were identified in the different wavelengths corresponding to the ZnO-CuO/GOr nanostructures.
