摘要
以电石和氯仿为碳源和反应物，二茂铁为催化剂，置于100ml的不锈钢高压釜中在350℃进行化学反应并保温3h，制备了50～150nm的无定形结构毛绒形貌碳球．采用X射线显微镜、扫描电子显微镜、透射电子显饭镜和激光拉曼光谱仪等手段分析碳球的物相、形貌和结构，并初步讨论了纳米碳球的生长机理．
With calcium carbide and chloroform as carbon sourses, and ferrocene as catalyst, and chemical reaction of CaC2-CHCl3 system was carried out at 350℃ for 3 hours, fluffy carbon namispheres with amorphous struture were fabricated. The phase, morphology and microstructure of carbon spheres were analyzed by XRD, SEM, TEM and Raman spectrum.. At last, the growth mechanism of carbon nanospheres issimply supposed.
