摘　　要：利用改进的电弧放电法,以CO_(2)为氧源,成功合成了一系列内嵌钬氧团簇富勒烯Ho_(2)O@C_(2n)(n=43-55)。通过对放电电流、反应室气体压力、反应室气体组成和催化剂种类等实验参数的调控,将内嵌钬氧团簇富勒烯的合成产率提高了数倍。发现在内嵌钬氧团簇富勒烯的电弧放电合成过程中,铁是较钴、镍和铜更佳的金属催化剂。A series of holmium-oxygen cluster fullerenes Ho_(2)O@C_(2n)(n=43-55)were successfully synthesized by an improved arc discharge method with carbon dioxide as oxygen source.The synthetic yield of holmium-oxygen cluster fullerenes was increased several times by adjusting experimental parameters including arc discharge current,the total pressure and composition of mixed gases in chamber,and metal catalyst species.It was found that iron is a better metal catalyst than cobalt,nickel or copper for the arc discharge synthesis of holmium-oxygen cluster fullerenes.
