摘要 提出一种采用共沉淀法制备三维多孔Fe3O4纳米花的合成方法,对Fe3O4纳米花的自组装演化过程进行了研究.结果发现,尿素浓度是影响Fe3O4前驱体形貌的关键因素,通过调节制备条件可以获得具有纳米花形貌的Fe3O4纳米颗粒,Fe3O4纳米花作为磁性多孔微球具有更高的比表面积.磁性测试结果表明,Fe3O4纳米花在室温下具有超顺磁性且具有较高的饱和磁化强度.该材料是一种具有较好应用前景的磁性纳米材料. In this paper,a method for preparing porous Fe3O4 nano-flowers by coprecipitation was proposed.The evolution process of self-assembly was studied.It was found that the urea concentration was the key factor for affecting the morphology of Fe3O4 nano-flowers.The Fe3O4 nano-flowers calcined under a nitrogen atmosphere had the superparamagnetism and high saturation magnetization at room temperature.Magnetic porous microspheres with higher specific surface area are promising magnetic nanomaterials.
