为了探究高温处理酞菁钴对O2 的催化还原作用 ,以酞菁钴作为催化剂的前体 ,通过化学气相沉积的方法 ,在 85 0℃下 ,氩气与氢气混合气流中 ,制备了双层定向碳纳米管 ,纳米管的直径分布在 6 0～ 12 0nm ,长度约为4 0 μm ,在纳米碳管中包裹有直径为 10nm的钴颗粒 .所得产品用透射电子显微镜和扫描电子显微镜进行了观察 ,并用拉曼谱和X射线衍射对样品进行了表征 .通过循环伏安法测量得到纳米碳管对金属颗粒在酸性溶液中的腐蚀具有一定抵抗作用 .认为少量的N对于竹节状碳纳米管的形成和金属对酸的抵抗作用是十分必要的 ,每节中碳壁的弯曲弧度则与N在碳纳米管中含量和N与金属的相互作用有关 .另外 ,碳纳米管较大的电化学活性区域在电化学方面具有潜在的应用价值 .
In order to explore the high temperature treatment of cobalt phthalocyanine on the catalytic reduction of O2, phthalocyanine cobalt as a catalyst precursor, by chemical vapor deposition method, at 85 ° C, argon and hydrogen mixed gas flow to prepare a two-layer orientation The diameter of carbon nanotubes and nanotubes were 60 ~ 120 nm and the length was about 40 μm, and the carbon nanotubes were coated with cobalt particles with a diameter of 10 nm. The obtained products were observed by transmission electron microscopy and scanning electron microscopy , And the samples were characterized by Raman spectroscopy and X-ray diffraction.The cyclic voltammetry obtained carbon nanotubes have certain resistance to corrosion of metal particles in acidic solution.A small amount of N for the bamboo-like carbon nanotubes Formation and metal resistance to acid is very necessary, each section of the curvature of the carbon wall and the N content in carbon nanotubes and N and metal interaction. In addition, the larger electrochemical carbon nanotubes The active region has potential application value in electrochemistry.
