中文摘要：

由臭氧处理的多围的碳 nanotubes (MWCNT ) 的 functionalization 被使用拉曼光谱学系统地调查了，传播电子显微镜学(TEM ) ， Fourier 变换红外线的光谱学(FTIR ) ， X 光检查光电子光谱学(XPS ) ，器官的元素的分析(OEA ) 和 Boehm 滴定。结果证明 functionalization 过程发生在有缺点的地点(张开的嘴，试管帽子，碎片，等等) 在打开帽子并且截断墙前，并且最后， graphitic 结构被败坏。表面氧内容首先与处理时间增加了，但是在 5h 以后在约 8.0 wt% 保留了。包含氧的组的分发的分析表明酉分的氢氧根逐渐地被变换成 carboxyl 和内酯。carboxyl 被发现起一个枢轴的作用当我们为氧减小反应(ORR ) 把 functionalized MWCNT 用作催化剂时，减少过电位。

英文摘要：

The functionalization of multi-walled carbon nanotubes （MWCNTs） by ozone treatment has been sys- tematically investigated by using Raman spectroscopy, transmission electron microscopy （TEM）, Fourier transform inhared spectroscopy （FTIR）, X-ray photoelectron spectroscopy （XPS）, organic elemental anal- ysis （OEA） and Boehm titration. The results showed that the functionalization process occurred at defective sites （opened mouths, tube caps, debris, etc.） before opening caps and truncating walls, and finally the graphitic structure was deteriorated. The surface oxygen content first increased with the treatment time but kept at around 8.0 wt% after 5 h. The analysis of the distribution of oxygen-containing groups re- vealed that phenolic hydroxyl was gradually converted to carboxyl and lactone, The carboxyl was found to play a pivotal role to reduce the over-potentials when we used the functionalized MWCNTs as the cat- alyst for oxygen reduction reaction （ORR）.
