【摘要】 采用直流电弧放电法以煤为原料制备富勒烯。实验采用工作气体为Ar,催化剂选用纳米Cu颗粒。所得到的阴极产物的HREM观察表明:在适当的工艺条件和催化剂作用下,可宏量制备出碳纳米颗粒—洋葱状富勒烯,直径为25-40nm;煤的独特结构使其在制备过程中沿两条路径形成富勒烯。EDS研究表明煤中的微量元素影响着洋葱状富勒烯的生成。更多还原

【Abstract】 Onion-like fullerenes were derived from coal by the DC arc-discharge method,using nano Cu particles as catalysttn the experiment the working gas was Ar. We applied a high resolution ansmission electron microscope (HREM)and energy dispersive spectrometry(EDS) in the study of the cathode deposit. The results indicated that the yield of onion-like fullerenes was high, with diameters of about 25-40mn. As the structure of coal is particular , onion-like fullerenes formed by two ways .EDS analysis indicated that there were micr-mineral elements have effects on the growth mechanisms of fullerenes.更多还原
