doi:10.3724/SP.J.1077.2011.00458

Abstract

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
