摘要:

 通过用掺有异相物质的石墨电极进行电弧反应,所得的混合物中大分子Fullerene的含量在10%以上,为进一步分离、提纯以及深入研究大分子Fullerene打下了基础. 研究发现,阳板材料中完整石墨结构的存在是生成Fullerene的必要条件,异相物质的存在为Fullerene的生长提供了热的载体,从而使产物中大分子Fullerene的含量增加.

Abstract:

 By the arc-discharge of carbon composite rods and graphite rods doped with other substances, fullerene mixture of containing about 10% of higher fullerenes was obtained. This provides the base for the separation, purification and further study of higher fullerenes. Moreover, it was found that the existence of perfect graphite structure in the anode rod is the necessary condition for the fullerene formation. Also, It was considered that other substance doped in the anode plays a role as the hot supports in the fullerenes' growing process, which is the reason of the high yield of higher fullerenes.
