Synthesis and Characterization of TiO2 /Fe3O4 Composites Using Sonication Method

TiO2/Fe3O4 composite was synthesized by sonication method using mass ratio of 10:1 then calcined at 400ºC for 2 hours. Characterization of TiO2/Fe3O4 composite was carried out using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM) instruments. The results of characterization of TiO2/Fe3O4 composite using XRD showed diffractogram results with a collection of Fe3O4 phases and TiO2 phases with a crystallinity value of 64.7%. FTIR analysis showed Ti-O-Ti vibrations appeared in the range of 700-900 cm-1 and absorption bands from Fe-O vibrations appeared at a peak around 600 cm-1. SEM analysis showed the morphology of TiO2 /Fe3O4 composite with Fe3O4 particles attached to the surface of TiO2 particles and forming a rough surface.
