Natural fullerenes - will they offer a hint to the selective synthesis of fullerenes?

摘要

In addition to the known laboratory methods of preparing fullerenes, which generally start from carbon vapor, studies of naturally occurring C_(60)/C_(70) suggest a catalytic process of fullerene formation that proceeds in solid phase under mild condition. Recent observation of C_(60)/C_(70) in Yunnan coal and Kalerian C-rich rock is reviewed in the light of the above perspective.
