TiO₂ is widely used in semiconductor photocatalysis due to its excellent features. However, TiO₂ particles with nanoscale is difficult to separate and recycle after the photocatalytic reactions. In this paper, we successfully synthesized the magnetic Fe₃O₄/TiO₂ composite by the simple and mild dip-molding method. Both the TiO₂ and Fe₃O₄ are originated by the cheap ilmenite as raw material. A series of characterization means including XRD, FT-IR, SEM and EDS were used to analyze the surface structure of the Fe₃O₄/TiO₂ composite. Furthermore, the performance of Fe₃O₄/TiO₂ composites was investigated by using of photocatalytic degradation of Rhodamine B (Rh B) as a probe reaction. The results demonstrated that the Fe₃O₄/TiO₂ composite with mass ratio of 1:10 are stable and uniform, has the best photocatalytic activity for Rh B, and shows outstanding recyclability. The photocatalytic degradation reaction coincides with the first-order reaction kinetics.
