一维碳化硅纳米材料的研究进展

Progress in Research on One-dimensional SiC Nanomaterials

介绍了具有一维纳米结构的碳化硅(SiC)如SiC纳米棒、纳米线、纳米管、纳米带的制备方法,着重介绍了碳纳米管模板生长法、碳还原法、激光烧蚀法、电弧放电法、流动催化剂法和热解有机前驱体法以及它们的生长机理,并对这几种方法的优缺点进行了分析,指出了目前研究一维纳米SiC中存在的问题和未来发展方向。

In this paper, the preparation methods for one-dimensional SiC nanostructures such as nanorods, nanowires, nanotubes and nanobelts are reviewed, emphasizing on the carbon nanotubes template-assisted growth （or the carbon nanotubes-confined reaction method）, the reduction method, the laser ablation synthesis, the arc-discharge approach, the floating catalyst method and pyrolysis of organic precursor. Their advantages and disadvantages are analyzed. The current problems and the development trend of the research on one-dimensional SiC nanomaterials are also pointed out.
