氮掺杂炭纳米管的合成及其在燃料电池和水处理方面的应用（英文）

Applications of Nitrogen-Doped Carbon Nanotubes in Fuel Cells and Water Treatment

在反应温度为700℃下,通过化学气相沉积(CVD)方法合成了竹节状氮掺杂炭纳米管。仲丁胺和负载铁Y型分子筛分别作为前驱体和催化剂。氮掺杂炭纳米管在氧化还原反应中的电催化性能是通过循环伏安方法检测的。循环伏安的检测结果表明氮掺杂炭纳米管的催化活性比负载铂的炭纳米管高。在含有Pb^(2+)离子的废水处理方面,氮掺杂炭纳米管也表现了较好的应用潜力。

Bamboo-like nitrogen-doped carbon nanotubes （NCNTs） have been synthesized by chemical vapor deposition （CVD） under 700℃. The butylamine and FeY zeolite have been used as precursor and catalyst, respectively. The electro- catalytic property of the NCNTs catalyst in oxygen reduction was examined by cyclic voltammetry. The results revealed that the NCNTs catalyst has higher catalytic activity than the commonly used Pt/C catalyst （Pt-CNTs, w （Pt/C） = 20%, BASF）. Another example of potential applications, NCNTs were used as adsorbent in waste-water treatment, and showed an excellent ability to remove Pb2＋ in water.
