摘　　要：用一步水热法制备出Fe3O4纳米颗粒,并最终组装成纳米级的Fe3O4空心球。用FIIR谱表征了样品的相结构,并用TEM和SEM表征样品的形貌,可以看出最后形成的纳米颗粒为空心球,粒径大约为200 nm,大小均一。In this paper. The hollow spheres were prepared by a simple hydrothermal route and characterized by TEM, SEM and FIIR. The results revealed that the sizes of nanoparticles were about 200 nm. The nanoparticles were spherical particles and had consistent size.
