介绍了以发泡Ni为催化剂、用CVD法生长节状纳米碳纤维的工艺过程，讨论了工艺参数对生成样品的产率和形貌的影响，同时还探讨了该样品的生长机理．认为催化剂的不同晶面分别有利于烃类气体的吸附解离或碳的沉积，因此催化剂颗粒的原始形貌影响了不同开貌的碳纤维生长． The process of growing nodular carbon nanofibers by CVD with foamed Ni as catalyst was discussed. The effects of process parameters on the yield and morphology of the samples were also discussed. The growth mechanism of the samples was also discussed. It is considered that the different crystal planes of the catalysts are conducive to the adsorption and dissociation of hydrocarbon gases or the deposition of carbon, respectively. Therefore, the original morphology of the catalyst particles affects the growth of carbon fibers with different open faces.
