我们描述了通过静电纺丝制备掺杂碳纳米管（CuO/C-NFs）或氧化镍（CuO/NiO-NFs）的氧化铜复合纳米纤维用于直接葡萄糖测定。人们对探索用于传感器应用的实用 CuO/C-NF 和 CuO/NiO-NF 电极材料的兴趣在于，它们可以在较低的过电势下促进动力学上不利的葡萄糖氧化反应的电子转移，从而提高电分析中电极对葡萄糖的选择性。通过扫描电子显微镜（SEM）和X射线粉末衍射（XRD）对CuO/C-NFs和CuO/NiO-NFs的形貌进行了表征。通过循环伏安法（CV）和计时电流法详细评估了葡萄糖的电催化性能。在直接葡萄糖电分析中，CuO/C-NFs 电极具有便利的电荷传输、增强的电流响应（在 +0.35 V 的较低过电势下）、改进的稳定性和选择性以及优异的抗电极污染性。这些优点归因于CuO/C-NFs电极材料的高度多孔三维网络膜结构以及复合纳米纤维中CuO和碳纳米管潜在的协同催化作用。这项研究可能为通过静电纺丝获得的金属氧化物基复合纳米纤维用于制造新型高性能传感器和设备提供新的见解。
We described the preparation of copper oxide composite nanofibers doped with carbon nanotubes (CuO/C-NFs) or nickel oxide(CuO/NiO-NFs) by electrospinning for direct glucose determination. The interest in exploring practical CuO/C-NFs and CuO/NiO-NFs electrode materials for sensor application was fascinated by the possibility of promoting electron transfer for kinetically unfavorable glucose oxidation reactions at a lower overpotential and thus improving the selectivity of the electrode for glucose in electroanalysis. The morphologies of CuO/C-NFs and CuO/NiO-NFs were characterized by scanning electron microscopy(SEM) and X-ray powder diffraction(XRD). The electrocatalytic performances of glucose were evaluated in detail by cyclic voltammetry(CV) and chronoamperometry. Facile charge transport, enhanced current response(at a lower overpotential of +0.35 V), improved stability and selectivity, as well as excellent resistance towards electrode fouling were observed at CuO/C-NFs electrode in direct glucose electroanalysis. These merits are attributed to the highly porous three-dimensional network film structure of CuO/C-NFs electrode materials and the potential synergic catalytic effect of CuO and carbon nanotubes in composite nanofibers. This study may provide a new insight into metal oxide-based composite nanofibers obtainedviaelectrospinning for fabricating novel and high performance sensors and devices.
