采用了电弧放电方法合成纳米炭管,在使用Fe、Co、Ni、Ti、Zr等金属元素作催化剂的基础上,探索天然矿物-黄铁矿(FeS2)、磁黄铁矿(Fe1-xS)、方铅矿(PbS)、磁铁矿(FeFe2O4)、刚玉(Al2O3)及合成FeCl3、NaCl、KCl等化合物作催化剂合成纳米炭管的途径,讨论其催化机理.实验说明:用矿物(化合物)作催化剂合成纳米炭管是可行的,并有应用潜力,其催化效果与电子层结构、化合物键性类型、晶体缺陷等密切相关.就催化效果而言,总体上表现出过渡金属元素催化效果优于非过渡金属元素,晶体结构中共价键程度高的化合物(含金属键或改性的共价键的化合物)催化效果好于离子键程度高的化合物.
