摘要：Platinum ion doped magnetic TiO2 (Fe3O4@SiO2@Pt-ion-TiO2) hybrid microspheres with uniform magnetic cores were synthesized and characterized in this work. The results indicate that the photoactivity of Fe3O4@SiO2@Pt-ion-TiO2 is much higher than Fe3O4@SiO2@TiO2 for the decolorization of acid orange 20 under UV-visible light irradiation. The trend for the final degradation ratio with Fe3O4@SiO2@Pt-ion-TiO2 is quite small, even after seven repetitive experiments. These data indicate that the magnetic microspheres possess the potential to be effective and stable catalysts. The results demonstrate that the Pt ion doped magnetic catalyst meets the needs for both immobilization and high photoactivity.
