摘　　要：纳米Fe3O4因其特殊的理化性质及在生物医学领域潜在的应用而得到广泛研究。本文综述了纳米Fe3O4的制备方法,包括直流电弧等离子体法、热分解方法、沉淀法、水热法、电化学法、微乳液法、溶胶-凝胶法、有机物模板法、回流法等,结合作者在Fe3O4纳米粒子制备方面的最新工作,介绍了纳米Fe3O4的新颖形貌。对纳米级Fe3O4制备研究的发展趋势进行了展望。Magnetite nanoparticles have been intensively concerned and researched in recent years due to their special properties in chemistry and physics and future applications in biology and medicine. More and more attentions have been paid to preparation methods as well as morphologic manipulation of magnetite nanoparticles since the characters and applications of magnetite nanoparticles are usually decided by their preparation method and shape. In this paper, preparation methods of magnetite nanoparticles are summarized, including DC arc plasma method, thermal decomposition method, ball milling method, co-precipitation method, hydrothermal method, sol-gel method, electrochemical process, micro-emulsion, template method and so on. The current work of authors in preparing magnetite nanoparticles with various morphologies such as octahedron, foursquare and polyhedron is presented. Such magnetite nanoparticles with novel octahedral shapes was synthesized and reported by authors for the first time, so did the foursquare and polyhedral magnetite nanoparticles. The development trends of methods of preparing magnetite nanoparticles are also discussed.
