摘要
采用溶剂热方法,以苯乙烯为还原剂和配位剂,合成了宽度为40nm-60nm、长度为600nm-1μm铋纳米带,并对其反应机理进行了探讨。在铋纳米带的合成中,α-铋的层状结构是形成铋纳米带的关键因素。配位试剂在各晶面的吸附对产物的形貌具有重要影响。通过改变配位试剂与铋盐的质量比,可以实现对铋纳米结构和形貌的调控。
In solvothermal conditions, styrene was taken to be reductant and complexant and bismuth nanobelts were synthesized. The width and the length of bismuth nanobelts are 40 nm-60 nm and 600 nm-1 μm respectively, the mechanism of the formation of bismuth nanobelts were discussed. The laminar structure of the -bismuth is the key factor for production of bismuth nanobehs. The morphology of bismuth nanostructures can be controlled by tuning up the molar ratio of complexant to Bi.
