| An easy chemical route for the synthesis of (γ-Fe2O3@SiO2)n@TiO2 functional hybrid nanoparticles is reported in this paper. The hybrid nanoparticles are composed of spherical nanoparticles about 100 nm in diameter, with several γ-Fe2O3 fine particles about 15 nm in diameter as cores distributing within the titania matrix and silica as coatings and barrier layers between the magnetic cores and titania shells. The (γ-Fe2O3@SiO2)n@TiO2 hybrid nanoparticles show good magnetic response and got together within 20 s in a magnetic field. Photodegradation examination of the magnetic hybrid nanoparticles was carried out in methylene blue solutions illuminated under UV light in a photochemical reactor. It is shown that the (γ-Fe2O3@SiO2)n@TiO2 functional hybrid nanoparticles are photocatalytically actived. About 80% of methylene blue decomposed in 80 min in the presence of magnetic hybrid nanoparticles under illumination of UV light. |

| 本文献报导了一种合成(γ-Fe2O3@SiO2)n@TiO2实用性混合纳米颗粒的简单的化学合成方法。混合纳米颗粒由直径约为100nm的球形纳米颗粒组成，由若干直径约为15nm的γ-Fe2O3 细微颗粒分布在二氧化钛基质中作为核心，并有二氧化硅作为磁性核心与二氧化钛壳之间的覆盖物及阻碍层。（这一长串话就是说15nm的γ-Fe2O3在中间是核心，核心外面是SiO2，最外面一层是二氧化钛。） (γ-Fe2O3@SiO2)n@TiO2混合纳米颗粒由良好的磁性响应，在磁场中20s内能聚到一起。在UV光照下的盛有亚甲蓝溶液光化学反应器中进行了纳米颗粒的光降解检测。结果表明(γ-Fe2O3@SiO2)n@TiO2实用性混合纳米颗粒具有光催化活性。在有磁性混合纳米颗粒的存在下，经UV光照射，约有80%的亚甲蓝在80min内被分解。 |
