摘　　要：文章采用沉淀转化法制得纳米氧化铜,后将其分散至N,N-二甲基甲酰胺,加入石墨烯利用简单超声法,将石墨烯分散到纳米氧化铜分散液中,得到纳米氧化铜/石墨烯复合材料,修饰在玻碳电极表面。利用差示脉冲伏安法进行对乙酰氨基苯酚的电化学检测实验,通过分析得出,与裸电极相比,纳米氧化铜/石墨烯复合材料修饰电极大幅度提高了对乙酰氨基苯酚在电极上的电化学响应信号,在20~900μmol范围内,响应电流随对乙酰氨基苯酚浓度的增加呈线性增长,电极具有良好的重现性和稳定性。In this paper,nanometer copper oxide was prepared by precipitation conversion method.Nanometer copper oxide was dispersed to N,N-dimethylformamide and graphene was added.By using a simple ultrasonic method,graphene was dispersed into nano copper oxide dispersion solution to obtain nano copper oxide/graphene composite material,which was modif ied on the surface of glassy carbon electrode.The electrochemical detection experiment of p-acetaminophenol was carried out by differential pulse voltammetry.The results showed that compared with the bare electrode,the electrochemical response signal of p-acetaminophenol modif ied by nano-copper oxide/graphene composite material was signif icantly improved.The response current increased linearly with the increase of p-acetaminophenol concentration in the range of 20-900μmol,and the electrode had good reproducibility and stability.
