摘    要:运用纳米Bi2O3微粒作催化剂,在电弧放电条件下,进行了纳米洋葱状富勒烯大量合成的研究。并用透射电镜对产物的形貌、结构进行了观察与分析。结果表明:纳米洋葱状富勒烯的石墨化程度很高,且直径均匀(约为25nm),结构较完善;同时伴有单核纳米洋葱状富勒烯向多核纳米洋葱状富勒烯的转变。为洋葱状富勒烯的宏量制备提供了有利线索。

关 键 词:电弧法  电弧放电  纳米洋葱状富勒烯  催化剂  纳米Bi2O3微粒  透射电镜  碳化学

Abstract:The synthesis of nano-onion-like fullerenes on a large scale by the arc discharge method was investigated using Bi_2O_3 as catalyst. Transmission electron microscopy was used to characterize the morphologies and microstructures of the product. Results indicated that the nano-onion-like fullerenes were perfectly structured and highly graphitized, with uniform external diameter of about 25nm. Two kinds of nano-onion-like fullerenes were obtained: 1) Single-nuclei onion-like fullerenes; 2) Multiple-nuclei onion-like fullerenes. The investigation pointed to a possible routine for large scale synthesis of onion-like fullerenes.
Keywords:Catalyst  Arc discharge  Nano-onion-like fullerenes
