摘　　要：没有表面活性剂存在的情况下,采用溶剂热法制备了一系列粒径均匀、分散性良好的Fe3O4亚微米空心球,并对其粒径、形貌和磁性进行了系统的研究。结果表明随着反应时间延长,Fe3O4亚微米粒子逐渐形成空心结构。该实验采用的方法不仅消除了表面活性剂的影响,而且设备和操作简单,具有良好的实验教学效果,可以作为应用化学专业无机功能材料方向的综合性实验项目。A series of nearly monodispersed Fe3O4 hollow spheres were fabricated by surfactant-free solvent-thermal method,and their particle size,morphology and the magnetism of the obtained samples were investigated in detail.It is found that the hollow structure of the Fe3O4 spheres become more and more prominent as increasing the reaction time.The present experiment has many advantages,such as elimination of the influence of surfactant,ease to operate and so on,thus can be applied as a comprehensive experiment of the experimental course of the applied chemistry in the area of inorganic functional materials.
