以氧化镍为催化剂,氯化石蜡为协效剂,聚丙烯为催化剂载体及部分碳源,通过简易CVD方法裂解C2H2气体可以高产率的得到一种条形海绵状的碳材料。利用扫描电子显微镜(SEM)、透射电子显微镜(TEM)和X射线衍射(XRD)对所得到的海绵状碳材料进行表征。结果表明这种条形海绵状碳材料是由粒径为300～500 nm的纳米碳球互相连接而成。 Using nickel oxide as catalyst, chlorinated paraffin as synergist and polypropylene as catalyst carrier and some carbon sources, C2H2 gas was pyrolyzed by simple CVD method to obtain a kind of bar sponge-like carbon material with high yield. The resulting sponge carbon material was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The results show that this kind of bar-shaped sponge carbon material is made of nanocarbon spheres with particle size of 300-500 nm.
