| 摘 要： | 采用一步水热法制备出针叶状的Fe3O4纳米颗粒,并最终组装成亚微尺寸Fe3O4空心球.用XRD、FIIR谱表征了样品的相结构.用TEM照片表征样品的形貌,可看出随着反应时间的延长,反应产物由针叶状的纳米颗粒最后组装成空心球.用VSM测量了样品的室温磁性,发现Fe3O4空心球表现出铁磁性.

| Abstract: | Magnetic Fe3O4hollow spheres were prepared by a simple hydrothermal route,and characterized by IR,XRD,TEM and VSM(vibrating sample magnetometer).XRD and FTIR results revealed that the state of matter and crystal structure of the as-prepared Fe3O4particles.TEM showed that acicular nanoparticles could grow and further transfer to hollow spheres with the prolonging of the reaction time.Magnetization curves indicated that the as-prepared Fe3O4 hollow spheres exhibited a ferromagnetic behavior. |
