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。

At the reaction temperature of 700 ℃, bamboo-like nitrogen-doped carbon nanotubes were synthesized by chemical vapor deposition (CVD). Secondary butylamine and iron-loaded Y zeolite were used as precursors and catalysts, respectively. The electrocatalytic activity of nitrogen-doped carbon nanotubes in a redox reaction was measured by cyclic voltammetry. The results of cyclic voltammetry show that the catalytic activity of nitrogen-doped carbon nanotubes is higher than that of platinum-loaded carbon nanotubes. Nitrogen-doped carbon nanotubes also show promising potential in the treatment of wastewater containing Pb 2+.
