提出了一种通用的方法，允许在碳基电极，否则潜在的嵌入介质的电活性物种的传感。已知石墨电极在含有高氯酸四正丁基铵作为支持电解质的碳酸亚丙酯溶液中会发生插层，导致剥离。然而，我们报告对比行为在竹多壁碳纳米管，其中嵌入/剥离不发生，因此允许有用的电分析测量，特别是用于安培测定氨。
A generic approach is presented allowing the sensing of electroactive species at carbon based electrodes in otherwise potentially intercalating media. Graphite electrodes are known to suffer intercalation leading to exfoliation in propylene carbonate solution containing tetra-n-butylammonium perchlorate as supporting electrolyte. However, we report contrasting behaviour at bamboo multiwalled carbon nanotubes, where intercalation/exfoliation does not occur, so allowing useful electroanalytical measurements to be made, in particular for the amperometric determination of ammonia.
