Morphological and structural properties of ZnO nanorods coated with graphene derivative fabricated by hydrothermal method

Abstract

In this work, graphene oxide coated ZnO nanorods composites were synthesized by hydrothermal method. Zn nitrate hexahydrate and hexametylenetetramine (HMTA) dissolved in deionized water used as solution growth of ZnO nanorods. Graphene oxide was prepared via modified Hummers method. Then, ZnO nanorods was coated with GO using the drop coating process. The structural properties of GO coated ZnO nanorods composite were analysed by scanning electron microscopy (SEM), X-ray diffraction (XRD) and the average crystallite size was determined by Debye-Scherrer formula. The experimental results obtained for our material exhibit significant enhancement in properties, which is suitable for the optoelectronic applications.
