A highly sensitive o-phenylenediamine (OPD) sensor based on a FeO doped with functionalized multi-walled carbon nanotubes (FeO@f-MWCNTs) composite fabricated glassy carbon electrode (GCE) was developed. The modified FeO@f-MWCNTs/GCE showed an enhanced current (I) response toward OPD relative to that of a FeO/GCE, f-MWCNTs/GCE, and a bare GCE. Under optimum conditions, the FeO@f-MWCNTs/GCE showed a wide linear range remove at OPD concentrations of 0.6-80µM. The limit of detection and sensitivity of the f-MWCNTs/GCE, FeO/GCE sensor were found to be 50µM, and 2.8002mAmMcm, respectively. The developed sensor showed excellent accumulation time, good repeatability, and operational stability. The obtained results suggest that the development of composite could be an effective electro-catalyst and it can play a vital role in biomedical, pharmaceutical, and hazardous free environmental applications.
一种基于掺杂功能化多壁碳纳米管的 FeO（FeO@f-MWCNTs）复合材料的高灵敏度邻苯二胺（OPD）传感器被制备出来，并将其修饰在玻碳电极（GCE）上。与 FeO/GCE、f-MWCNTs/GCE 和裸 GCE 相比，修饰后的 FeO@f-MWCNTs/GCE 对 OPD 表现出增强的电流（I）响应。在最佳条件下，FeO@f-MWCNTs/GCE 对 OPD 的浓度在 0.6-80µM 范围内呈现出宽的线性范围。发现 f-MWCNTs/GCE、FeO/GCE 传感器的检测限和灵敏度分别为 50µM 和 2.8002mAmMcm。该开发的传感器表现出良好的积累时间、良好的重复性和操作稳定性。结果表明，复合材料的开发可以作为一种有效的电催化剂，在生物医学、制药和无害环境应用中发挥重要作用。
