Abstract
In two types of coal from a coal mine in Yunnan Province, Southwestern China, the presence of fullerene is confirmed. The fullerene had been suggested earlier by its characteristic infrared absorption spectrum. The present work reports verification by a high performance liquid chromatograph. A critical step leading to the confirmation is in the process of preparation of the liquid solution from the coal for chromatography and this is described. Possible conditions for the search of natural fullerenes are suggested.
