研究了不同碳纳米材料修饰的玻碳（GC）电极上碱性溶液中氧的电还原。在0.1 M KOH条件下，采用旋转圆盘电极和旋转环圆盘电极进行了电化学实验。以聚四氟乙烯为粘结剂，用碳纳米材料对GC圆盘电极进行改性。使用了四种不同的碳纳米材料：多壁碳纳米管、炭黑粉末和两种碳化物衍生碳（CDC）。首次探讨了CDC材料对氧还原的电催化行为。材料的电化学表征表明，碳纳米材料修饰的气相色谱电极在碱性溶液中具有很强的氧还原活性。
Electroreduction of oxygen in alkaline solution on glassy carbon (GC) electrodes modified with different carbon nanomaterials has been studied. Electrochemical experiments were carried out in 0.1 M KOH employing the rotating disk electrode and rotating ring-disk electrode methods. The GC disk electrodes were modified with carbon nanomaterials using polytetrafluoroethylene as a binder. Four different carbon nanomaterials were used: multiwalled carbon nanotubes, carbon black powder, and two carbide-derived carbons (CDC). For the first time, the electrocatalytic behavior of CDC materials toward oxygen reduction is explored. Electrochemical characterization of the materials showed that all the carbon nanomaterial-modified GC electrodes are highly active for the reduction of oxygen in alkaline solutions.
