Preparation and Investigation of Structural and Surface Morphology Properties of ZnO Nanorods for Possible Environmental Applications

In the present work, Zinc oxide Nanorods (ZnO NRs.) was prepared by using the chemical bath method and separating the resulting precipitate by centrifugation. The most important physical properties of nanorods such as optical, morphological and structural properties were diagnosed and studied by "X-ray diffraction (XRD), field-emission scanning electron microscope (FE-SEM), energy dispersive X-ray (EDX), as well as UV-visible spectroscopy". The results of XRD showed that the prepared material has a hexagonal crystal structure and is of high purity, as there are no peaks due to impurities. The formation of zinc oxide was also proven by means of EDX, the weight ratio of zinc and oxygen was 85% and 15%, respectively. The energy gap of prepared rods was equal 3.3 eV.
