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