摘要石墨通常用于合成富勒烯和纳米管。然而，煤炭是一种更便宜、更适合工业的材料。由于煤是分子固体，与石墨不同，富勒烯和纳米管的形成机理是不同的。此外，还形成了其他产品，如多环芳烃(PAHs)和超细纤维。本文对煤中富勒烯和纳米管的形成机理进行了讨论。结果表明，所涉及的途径不是通过C_1中间路线。还讨论了煤中氢、氧、硫、铁等元素的影响。氢、氧、铁和硫似乎影响了富勒烯和纳米管的产量和类型。
Abstract Graphite has normally been used to synthesise fullerenes and nanotubes. However, coal is a cheaper and more suitable industrial material. Because coal is a molecular solid, unlike graphite, the mechanism by which fullerene and nanotubes are formed is different. Moreover, other products such as polyaromatic hydrocarbons (PAHs) and microfibres are also formed. In this review, the mechanism of formation of fullerene and nanotubes from coal is discussed. It is shown that the pathway involved is other than through the C1 intermediate route. The influence of other elements in coal such as hydrogen, oxygen, sulfur and iron is also discussed. It appears that, hydrogen, oxygen, iron and sulfur affect the yield and type of fullerenes and nanotubes formed.
