摘　　要：通过溶剂热法成功地制备了Fe3O4纳米粒子.结构与尺寸分析表明:所制备的Fe3O4纳米粒子为立方相结构,平均粒径30nm,尺寸均一,分散性较好.将Fe3O4纳米粒子应用于有机染料(如亚甲基蓝、藏红T)光催化降解实验发现,所制备的Fe3O4纳米粒子具有优异的光催化降解性能,降解率较高,且3次重复实验光催化效果接近.此外,制备的Fe3O4纳米粒子在室温下还具有很强的饱和磁化强度,可以实现光催化剂与染料溶液的分离,避免二次污染.Nanosized Fe3O4 have been successfully synthesized through a simple hydrothermal method.The results showed that the as-prepared Fe3O4 nanoparticles were cubic structure and had the mean diameter of 30 nm.The photocatalytic activity experiments toward some organic dyes（such as Methylene Blue,Safranine T）indicated that the as-prepared Fe3O4 nanoparticles exhibited superior photocatalytic degradation activity and also had good stability after three cycles.Moreover,the as-prepared Fe3O4 nanoparticles showed high magnetization saturation value at room temperature,which made it possible to realize convenient separation in water treatment process and thus reduced secondary pollution.
