摘要
采用石墨等离子体放电方法,建立了一套高效率制备C_(60)系列的工艺,成功地得到了纯的C_(60)。结果表明,反应气氛、电流密度与电极间距是影响制备过程的主要因素,氧化铝的活性、粒度及色谱柱的装填质量决定着C_(60)的分离效果。
A highly efficient preparation technique of fullerenes is developed by using the graphite-plasmadischarge method and C_(60) is successfully prepared. The results show that the atmosphere, current densityand the gap distance between two graphite electrodes affect the preparation efficiency of the fullerenes andthe activity, particle size and full quality of column chromatography of neutral alumina are the main factorsto control the purification of C_(60) in the fullerenes.
