ZnO Nanorods Synthesized by Hydrothermal Method Doped with Nanomaterials (Au, Cu, Pt, Ni, and Gr): Structural Properties Comparative Study

Abstract

In this research, ZnO nanorods were prepared successfully using the hydrothermal method. Pure ZnO was doped with many nanoparticles (Au, Cu, Pt, Ni, and Gr), and the effect of these dopants on the structural and morphological properties was examined. X‑ray diffraction (XRD) showed the formation of a hexagonal wurtzite structure crystal in all Pure and doped samples with an average particle size of ~11nm and some weak peaks of dopant crystalline nanoparticles. The surface morphology of undoped and doped ZnO with nanoparticles was investigated using scanning electron microscopy (SEM), and it was observed to be a nanorod. Atomic force microscopy (AFM) images have shown that surface and morphology roughness were influenced by doping. FTIR spectroscopy has been used to investigate the functional groups in forming pure and doped ZnO.
