Abstract

SYNTHESIS AND CHARACTERIZATION OF Fe3O4@ZnO COMPOSITE THROUGH PRECIPITATION METHOD. Fe3O4@ZnO composite has been synthesized trough precipitation method with the ratio between Fe3O4 and ZnO are 1:1, 1:2, dan 1:3. Characterization of the sample was performed using X-ray diffractometer (XRD), scanning electron microscope (SEM) equipped with energy dispersive spectrophotometer (EDS), vibrating sample magnetometer (VSM) and transmission electron microscope (TEM). The XRD pattern shows that the sample consisted of Fe3O4 nanoparticles and ZnO phases. Magnetic saturation value (Ms) of Fe3O4 were measured by VSM obtained about 62.92 emu / g, but then the value of Ms dropped to13.60 emu/g with the addition of ZnO content. TEM observation showed a spherical structure of Fe3O4 aggregate about 20 nm in diameter, and embedded in the ZnO shell. EDS spectrum revealed that the Fe3O4@ZnO composites were only observed three types of elements, namely Fe, Zn and O. This shows evidence that the coating on the surface of Fe3O4 nanoparticles is the outer shell of ZnO. Fe3O4@ZnO composites with Fe3O4 and ZnO ratio is 1: 2 shows a more homogeneous coating ZnO.
