摘要 以MOF-5为模板,采用原位生长法和高温碳化法制备了立方形貌的ZnO/ZnS纳米材料。利用扫描电子显微镜(SEM)和X-射线衍射(XRD)技术对ZnO/ZnS纳米材料的形貌和结构进行分析。合成好的ZnO/ZnS材料作为电极传感材料制备电化学传感器,并用于木犀草素的快速电化学检测。结果表明,与裸玻璃碳电极(GCE)相比,所制备的目标电极(ZnO/ZnS/GCE)对木犀草素有良好的电化学响应。在优化条件下,ZnO/ZnS/GCE对木犀草素的检测展现出较宽的线性范围和较低的检出限。同时,该修饰电极也表现出良好的重复性、再现性和抗干扰性能。且ZnO/ZnS/GCE成功地应用于独一味胶囊中木犀草素含量的测定,回收率良好。实验结果表明,ZnO/ZnS/GCE是木犀草素电化学检测良好的备选电极之一。 Using MOF-5 as template to prepare cubic ZnO/ZnS nanomaterials by in-situ growth method and high temperature carbonization method.The morphology and structure of ZnO/ZnS nanomaterials were analyzed by SEM and XRD.The synthesized ZnO/ZnS material was used as electrode sensor to prepare electrochemical sensor,and was used for the rapid electrochemical detection of luteolin.Result showed that compared with bare glass carbon electrode(GCE),the prepared target electrode(ZnO/ZnS/GCE)has a good electrochemical response to luteolin.Under the optimized conditions,ZnO/ZnS/GCE showed a wide linear range and low detection limit for luteolin.At the same time,the modified electrode also showed good repeatability,reproducibility and anti-interference performance.And ZnO/ZnS/GCE was successfully applied to the determination of luteolin in Duyiwei capsules with good recovery.The results show that ZnO/ZnS/GCE is one of the good candidate electrodes for the electrochemical detection of luteolin.
