摘要

氧化还原介质甲苯胺蓝（TBO）自组装到N

S共掺杂多孔碳（N

S@PC）表面，制备了一种新的电化学复合物（N

S@PCTBO）。N

S@PC和N

S@PC-TBO复合物通过扫描电镜进行表征，两者表面形貌有明显的不同。N

S@PC-TBO复合物用来修饰玻碳（GC）电极，具有很高的导电性能。通过循环伏安和安培实验表征N

S@PC-TBO/GC电极的电催化行为。实验结果表明，N

S@PC-TBO/GC电极具有N

S@PC和TBO两者电催化氧化NADH的协同效应。N

S@PC-TBO/GC电极检测NADH的线性范围为1×10

－6

- 2×10

－3

mol/L，检测限为3×10

－7

mol/L（信/噪 = 3），响应时间为2 s。因此，制备的N

S@PC-TBO/GC电极为NADH的检测提供了较好平台。

Abstract

A new electrochemical composite is reported

which is based on redox mediator toluidine blue O (TBO) self-assembled onto the surface of nitrogen

phosphorus and sulfur codoped porous carbons (N

S@PC). The N

S@PC and N

S@PC-TBO composites were characterized by scanning electron microscopy and the results showed surface morphology of the two composites was distinctly different. The N

S@PC-TBO composite was used to modify glass carbon (GC) electrode which displayed high conductivity. The electrocatalytic behaviour of N

S@PC-TBO/GC electrode was studied by voltammetry and amperometry. The results demonstrated that the N

S@PC-TBO/GC electrode provided a positively synergistic effect between N

S@PC and TBO on the electrocatalytic oxidation of NADH. This modified electrode exhibited a wide linear range from 1×10

－6

- 2×10

－3

mol/L and a detection limit of 3×10

－7

mol/L (

S/N

= 3) with a fast response time of 2 s

at a low applied potential of－0203 V. Therefore

the N

S@PC-TBO/GC electrode provides a new platform for the detection of NADH.
