Abstract
The synthesis of Fe3O4 – ZnO nanocomposite results is an interesting research currently which its application can be used in many ways such as gas sensor application. This research aimed to analyze the structure of magnetite (Fe3O4) - Zink Oxide (ZnO) nano composite through hydrothermal method. The procedures of Fe3O4 – ZnO nanocomposites synthesis started when Fe3O4 nanoparticles were decorated and added with ZnO. The proses of hydrothermal conducted at 180 °C for 12 hours then the synthesis results were cleaned by using water and etanol. The next step was calcined for 2 hours at 500°C and Fe3O4 – ZnO nanocomposites as the results. The sample of Fe3O4 – ZnO nanocomposites then characterized by X-ray diffractometer (XRD) and the pattern indicated the cubic structure index. The nanocomposites structure showed several peaks which were tapered up and the width narrowed. The results of XRD also described nanocomposite sample material has crystalline phase structure for 73.9% and of which 26.1% was amorphous.
