【摘要】 利用一步电化学原位还原法制备了还原氧化石墨烯/多壁碳纳米管复合物（ErGO/MWCNTs）,研究木犀草素在该复合物修饰电极（ErGO-MWCNTs/GCE）上的电化学行为,构筑了一种简易、灵敏的电化学传感器用于木犀草素的检测。结果表明,相较于裸电极和ErGO/GCE,ErGO-MWCNTs/GCE利用两种材料的协同作用有效促进了对木犀草素的电催化性能,表现出更灵敏的电流响应。在优化条件下,峰电流与木犀草素的浓度在2.5×10^-7～1.3×10^-5 mol·L^-1范围内呈良好线性关系,检测限为70 nmol·L^-1。更多还原

【Abstract】 A simple and sensitive electrochemical sensor was constructed for luteolin detection based on the electrochemical behavior of luteolin on the composite modified electrode（ErGO-MWCNTs/GCE）.The reduced graphene oxide/multi-walled carbon nanotube composite（ErGO/MWCNTs）was prepared by a one-step electrochemical in-situ reduction method.The results showed that, compared with the bare electrode and ErGO/GCE,ErGO-MWCNTs/GCE showed better electrocatalytic capability for Luteolin because of the positive synergistic electrocatalytic capability of the two materials.Under optimal conditions, the peak current showed a good linear relationship with luteolin concentration in the range of 2.5×10^-7～1.3×10^-5 mol·L^-1 and the detection limit was 70 nmol·L^-1.更多还原
