摘要/Abstract

摘要： 铁氧化物纳米材料和纳米结构空心微球分别代表了材料研究中组分和结构的研究热点. 而由铁氧化物纳米晶自组装形成的空心微球的研究则是二者相结合, 具有重要的科学意义和良好的应用前景. 虽然已发展了多种方法制备各种单质及化合物的空心微球, 但铁氧化物纳米晶自组装空心微球的制备方法报道较少. 本文简要介绍了近几年发展起来的多种铁氧化物纳米晶自组装空心微球的一些制备方法, 利用上述方法, 制备出了多种不同组成单元、不同尺寸、不同空心程度的铁氧化物纳米晶自组装空心微球, 对所制备的铁氧化物纳米晶自组装空心微球进行了表征, 并初步介绍了所制备的铁氧化物纳米晶自组装空心微球在药物缓释和环境领域中的应用.

Abstract: Nanostructured hollow microspheres of iron oxides are promising for the applications in the fields of magnetic storage media, catalysis, pigments, adsorbents, biomedicine, sensors, etc., due to their low toxicity, excellent magnetic properties, chemical stability, biocompatibility, corrosion resistance, low density and high specific surface area. The investigation on hollow microspheres assembled with nanocrystals of iron oxides is of especially scientific interest and technological importance. Herein, we briefly review several novel methods that have been developed in recent years for the preparation of nanostructured hollow microspheres of iron oxides constructed by self-assembly with different building blocks, sizes and hollow interiors. And the potential applications of the as-prepared iron oxide hollow microspheres in the fields of drug delivery, adsorption and photocatalysis are also discussed.

Key words: iron oxide, hollow microsphere, nanocrystal, self-assembly, review
