The electrochemical activity of stacked nitrogen-doped carbon nanotube cups (NCNCs) has been explored in comparison to commercial Pt-decorated carbon nanotubes. The nanocup catalyst has demonstrated comparable performance to that of Pt catalyst in oxygen reduction reaction. In addition to effectively catalyzing O(2) reduction, the NCNC electrodes have been used for H(2)O(2) oxidation and consequently for glucose detection when NCNCs were functionalized with glucose oxidase (GOx). Creating the catalysts entirely free of precious metals is of great importance for low-cost fuel cells and biosensors.
我们研究了堆积氮掺杂碳纳米管杯（NCNC）的电化学活性，并将其与商业 Pt 修饰碳纳米管进行了比较。纳米杯催化剂在氧还原反应中表现出与 Pt 催化剂相当的性能。除了有效催化 O(2)还原外，NCNC 电极还可用于 H(2)O(2)氧化，并且当 NCNC 用葡萄糖氧化酶（GOx）功能化时，可用于葡萄糖检测。完全不使用贵金属制造催化剂对于低成本燃料电池和生物传感器非常重要。
