摘　　要：通过水热合成法将钯铜(PdCu)纳米粒子负载于多壁碳纳米管(MWCNTs),从而制备了多壁碳纳米管钯铜纳米复合材料(PdCu@MWCNTs)。该复合物电子传递阻力低,比表面积大,具有良好的电催化活性。将该纳米复合材料修饰在玻碳电极上实现了对乙酰氨基苯酚(PCT)的灵敏检测。在最优的实验条件下,峰电流与对乙酰氨基苯酚浓度在0.15μmol/L~60μmol/L之间线性良好,相关系数R^(2)=0.990,检出限(S/N=3)为0.13μmol/L。该传感器具有良好的选择性,稳定性和重复性,可用于市售剂中对乙酰氨基苯酚的检测。Multi-walled carbon nanotube and palladium-copper nanocomposite(PdCu@MWCNTs)was prepared by hydrothermal method.The composite had low electron transfer resistance,large specific surface area,and good electrocatalytic activity.The sensing platform of paracetamol(PCT)was developed based on multi-walled carbon nanotube palladium copper nanocomposite dropped-cast on the glassy carbon electrode(GCE).Under optimized conditions,the current increased with the concentration of paracetamol between 0.15μmol/L and 60μmol/L,and the detection limit was 0.13μmol/L.The developed sensor had high selectivity,good stability,excellent repeatability,and had a good recovery rate of paracetamol in the commercial agent.
