Endohedral metallofullerene Ce@C-60 has been enriched in the extracted
solution of the soot prepared by are-heating of CeO/graphite composit
e rods. The enrichment of Ce@C-60 in aniline solution containing the h
ollow and the other endohedral fullerenes have been performed by using
high performance liquid chromatography (HPLC) technique. The laser de
sorption time-of-flight(LD-TOF) mass spectrum shows clearly the enrich
ment of Ce@C-60.
