摘要

In recent years,with the increasing requirements for the preparation of high-purity,advanced and complex inorganic nanomaterials,the microwave-assisted synthesis method has gradually shown tremendous development prospects.Nanomaterials prepared by microwave-assisted synthesis have been widely used in many fields due to their high purity,narrower particle size distribution and more uniform morphology.In this paper,the mechanism,progress and application status of advanced nanomaterials prepared by microwave method are summarized.The new progress of transition metal oxides nanostructures prepared in aqueous solution,polyols and ionic solution system are mainly discussed.The examples of microwave-assisted synthesis of α-Fe2O3 and TiO2 advanced nanostructures and their applications in lithium-ion batteries or photocatalysis will be introduced.Finally,the development trend and challenges of microwave synthesis method are prospected.%近年来,随着制备高纯度的先进复杂纳米材料的要求愈发提高,微波辅助合成法已逐步表现出巨大的发展前景.微波合成法制备的纳米材料具有较高的纯度、更窄的粒径分布和更为均一的形态等优异特性,这使得该方法在许多领域获得了广泛的应用.综述了微波合成法制备纳米材料的工作机制、应用现状和研究进展,分类阐述了在水溶液、多元醇、离子溶液体系下制备过渡金属氧化物的新进展,重点讨论了微波辅助合成法制备α-Fe2O3和TiO2先进纳米材料及其在锂离子电池、光催化中的应用,最后展望了微波合成法的发展趋势及面临的挑战和机遇.
