研究了用于葡萄糖非酶电化学传感的碳纳米纤维(CNFS)/Co(OH)2纳米复合材料的合成。将Co(NO3)2和CNFS的混合物在50 V乙醇中电泳沉积2 min，制备了传感基质。用x射线光电子能谱、扫描电镜和循环伏安法对合成的CNFS/Co(OH)2基质进行了表征。测试了其在0.1 M NaOH溶液中对葡萄糖氧化的电催化性能。检测限为5µM，线性范围为10µM ~ 0.12 mM。目前的反应对葡萄糖是选择性的，并且随着时间的推移是稳定的。该纳米复合材料具有良好的分析性能，可用于检测真实人血清样品中的葡萄糖。
The synthesis of carbon nanofibers (CNFS)/Co(OH)2 nanocomposites for non-enzymatic electrochemical sensing of glucose is presented. The sensing matrix was fabricated by electrophoretic deposition of a mixture of Co(NO3)2 and CNFS in ethanol at 50 V for 2 min onto gold electrodes. The formed CNFS/Co(OH)2 matrix was characterised by X-ray photoelectron spectroscopy, scanning electron microscopy and cyclic voltammetry. Its electrocatalytic properties towards the oxidation of glucose in 0.1 M NaOH were tested. A detection limit of 5 µM with linearity of 10 µM to 0.12 mM was obtained. The current response was selective towards glucose and stable over time. The good analytical performance of the nanocomposite allowed for sensing glucose in real human serum samples.
