简易水热法制备磁性Fe3O4纳米颗粒及其磁性能研究
Preparation and Magnetic Performance of Magnetic Fe3O4 Nanoparticles by Facile Hydrothermal Method
摘要
Abstract
Magnetic Fe3O4 nanomaterials have excellent magnetic properties including high magnetic response,superparamagnetism and biocompatibility.By regulating the microscopic morphology of the materials,it is possible to achieve effectively control of its physical and chemical properties,such as energy storage,catalysis and medicine,in accordance with the requirements of practical applications.In this paper,according to modify the conditions including the ratio of Fe3+and Fe2+in the precursor,reaction temperature and reaction time,spherical magnetic Fe3O4 nanoparticles with particle sizes ranging from 10 to 25 nm were synthesized by a facile hydrothermal method without the addition of a morphology modifier.And the saturation magnetization intensity of the material under the optimum conditions was 73.3 emu·g-1.The results show that the magnetic properties of Fe3O4 nanoparticles have a clear relationship with the preparation conditions.With the increase of hydrothermal temperature and time,the particle size and saturation magnetization intensity of magnetic nanoparticles increase first and then decrease.The smaller the particle size is,the smaller the internal magnetic effective volume is,and therefore the lower the saturation magnetization intensity is.关键词
