摘要

在惰性气氛下高温煅烧硫氰酸钴和三聚氰胺的混合物，得到大量均匀的钴硫氮共掺杂碳纳米管材料．利用X-射线粉末衍射仪、扫描电子显微镜、透射电子显微镜、拉曼光谱仪等对得到的钴硫氮共掺杂碳纳米管进行表征，结果表明：其具有规整的竹节状结构，Co纳米粒子位于碳纳米管顶端，且钴、硫、氮原子成功地掺入到碳纳米管中．电化学测试结果表明：钴硫氮共掺杂碳纳米管在0.1 mol/L KOH氧饱和溶液中具有优异的氧还原催化活性，测得起始电位为-0.12 V，半波电位为-0.16 V，极限扩散电流密度为-5.62 m A·cm-2．该合成方法简单易行，为制备非贵金属基氧还原电催化剂提供了参考．

Abstract

A large number of uniform cobalt sulfur nitrogen doped carbon nanotubes were obtained by calcining the mixture of cobalt thiocyanate and melamine. The cobalt sulfur nitrogen doped carbon nanotubes were characterized by X-ray difraction

scanning electron microscope

transmission electron microscope and Raman spectrometer. The results show that the carbon nanotubes have regular bamboo-like structure and the Co NPs are encapsulated in the tips of carbon nanotubes. In addition

cobalt

sulfur

nitrogen atoms are doped in carbon nanotubes successfully. The electrochemical test results show that the cobalt sulfur nitrogen doped carbon nanotubes have excellent catalytic activity of oxygen reduction in O2 saturated 0.1 mol/L KOH. The positive onset potential is-0.12 V

half-wave potential is-0.16 V

and difusion-limiting current density is-5.62 m A·cm-2. The synthesis method is simple and feasible

which provides reference value for preparing non-noble metal-based oxygen reduction electrocatalyst.
