英文摘要：

The mechanical stability of the electrode plays a very important role in the long term stability of electrochemical behavior. In this paper, carbon nanotubes（CNTs） electrodes are prepared in the holes of glass directly by microwave plasma chemical vapor deposition and the electrochemical behavior of catechol at the integrated CNTs electrodes is investigated. The oxygen plasma treated CNTs have excellent electrochemical behavior for the analysis of catechol. The catechol is detected in the linear concentration range of 1.0 × 10^-6 -1.0 ×10^-3 mol· L-1. And because CNTs are integrated directly on the substrate, the stable response to catechol solution shows that the carbon nanotubes electrodes have long-term stability.
