摘　　要：本研究利用常温合成法制备得到MWCNTs@ZIF-67;以其作为模板,热解得到MWCNTs@N-Co-C复合物。将此复合物用于构建测定木犀草素(LUT)的电化学传感器。通过X射线粉末衍射(XRD)、扫描电子显微镜(SEM)和X光电子能谱(XPS)对该复合物的形貌结构进行表征。在最佳实验条件下,LUT在1.00×10^(-8)~1.00×10^(-4)mol/L浓度范围内线性关系良好,检出限为3.03×10^(-9)mol/L。该传感器用于检测实际菊花茶样品,结果满意。In this work,MWCNTs@ZIF-67 was prepared by ambient temperature synthesis method.As a template,MWCNTs@ZIF-67 was pyrolyzed to produce MWCNTs@N-Co-C complex,which was applied for the construction of electrochemical sensor to detect luteolin(LUT).X-ray powder diffraction(XRD),scanning electron microscopy(SEM),and X-photoelectron spectroscopy(XPS)were applied to characterize the morphological structure of the prepared complex.Under optimal experimental conditions,LUT showed a good linearity in the concentration range of1.00×10^(-8)-1.00×10^(-4)mol/L with the detection limit of 3.03×10^(-9)mol/L.The sensor achieved satisfactory results for detecting LUT in actual chrysanthemum tea samples.
