摘要:
为了提高碳纳米管的氧还原性能，利用氨等离子体对碳纳米管进行了表面改性处理. 采用透射电子显微镜、拉曼光谱对改性前后碳纳米管的结构进行了表征，利用电化学方法比较分析了改性前后碳纳米管的氧还原性能. 研究发现，氨等离子体改性对碳纳米管的结构未产生明显的影响，改性后ID/IG值无变化，但改性后碳纳米管的氧还原起始电位为-146 mV、半峰电位高-243 mV、动力学电流为17.42 mA/cm2、电子转移数目为3.0，其均高于碳纳米管的相应参数. 等离子体表面改性工艺简单，改性后对氧还原性能显著提高.
Abstract:
The carbon nanotube was modified with ammonia plasma to improve its oxygen reduction performance. The structure and morphology of the samples were characterized by transmission electron microscope and Raman spectra. The oxygen reduction performance of the carbon nanotube was analyzed through electrochemical test. The result shows that the structure, morphology and the ID/IG value of the carbon nanotube have no significant change after the ammonia plasma modification. However, the oxygen reduction ability has some improvement. The values of onset potential, half peak potential, kinetics current and electron transfer number are -146 mV, -243 mV, 17.42 mA/cm2 and 3.0, respectively, which are higher than those of the unmodified carbon nanotube. The technology of plasma surface modification is simple and remarkably improves oxygen reduction performance of the carbon nanotube.
