摘要
过渡金属镍纳米粉体是未来最有前途的新型催化剂之一,尤其在军事领域日趋重要。制备方法和工艺是决定纳米镍粉的组成、结构和性质的主要因素。而后处理是解决目前纳米镍粉大规模工业化应用的关键技术。本文综述了近年来国内外应用较多的纳米镍粉的制备方法,分别就气相法、液相法和固相法中纳米镍粉具体制备方法的优缺点和应用现状进行了评述;介绍了纳米镍粉后处理在实际应用中的重要性,并详尽评述了纳米镍粉的纯化、分散和表面保护等后处理的具体技术方法;最后对纳米金属镍粉制备的发展趋势给出了自己的观点。
Transition-metal nickel nanoparticles will be one of the most promising catalyzers in the future,especially will represent increasing significance in military affairs. Synthesis approaches and technology are determining elements,which influence composition、crystal structure and property of nickel nanoparticles. Furthermore,treatment technology is the chief technique to make the application of nickel nanoparticles as an industrialized mass production. In this paper,various synthesis approaches such as gas phase,liquid phase and solid phase methods of nickel nanoparticles mostly used in resent years are summarized,and the advantages、the disadvantages and the application status in industry,of every actual synthesis approaches are reviewed. The importance of treatment technology is introduced; and the material technology of purification、dispersion and surface protection is discussed in details. Finally,the developmental trend of the synthesis technology is put forward.
