【摘要】 超细空心粉末由于其特殊的结构和性质在国内外引起了研究者的极大兴趣。本文介绍了超细空心粉末的制备方法的最新研究进展。制备方法一般可分为雾化热分解法、置换反应法和模板法,并简单介绍了由本实验室提出的利用自催化还原反应制备空心镍粉的方法,这种方法的进一步研究正在本实验室开展。同时对超细空心粉末在化工、生物制药、军事工业和光学等领域的应用进行了概述。更多还原

【Abstract】 Increasing interest has been given to the micrometer and nanometer with hollow structures because of their specific morphologies and functions. The methods of synthesis and potential applications of the hollow structures were reviewed in this paper. The methods for preparing the superfine hollow spheres can be catalogued as spray drying, replacement reaction and templating method. Besides, a facile method presented by our group, for synthesizing hollow nickel spheres through autocatalytic reduction, is also briefly introduced, and the related work of this method is underway in our group now.更多还原
