Abstrak | : | Synthesis and Characterization of Magnetized Photocatalyst Fe3O4/SiO2/TiO2 by Heteroagglomeration Method Corresponding author : hasyarri@batan.go.id Abstract. Magnetic photocatalysts Fe3O4/SiO2/TiO have been prepared using heteroagglomeration method. Synthesis of magnetic photocatalyst Fe3O4/SiO2/TiO was carried out through four stages : (1) synthesis of photocatalyst TiO2 nanoparticles by TiCl coprecipitation in ammonia solution, (2) synthesis of Fe3O4 nanoparticles through precipitation method using a mixture of Fe (III) / Fe (II) (2: 1 mole ratio) in ammonia solution, (3) coating with SiO2 through hydrolysis of silicate ion, (4) in the final stage, Fe 43O4/SiO2 was mixed with TiO2 in hetero-agglomeration manner. Structure and morphology of resultan composites have been investigated by X-ray diffraction (XRD), Vibrating sample magnetometer (VSM), Fourier transform infrared (FTIR) and Transmission electron microscopy (TEM) were confirmed that composite Fe3O4/SiO2/TiO2 succefully synthesized. The functionality photocatalyst of the particles was tested by eliminating of methylene blue (MB) under UVlight. The result showed the magnetite photocatalyst Fe2O4/SiO2/TiO2 has phototacalytic and absorbtion properties so that it has good performance at dyes removal in water higher than pure TiO2, and capable to perform repeatition process at least 4 times. |
