    Pt颗粒/碳纳米管电极对L-半胱氨酸的电化学催化检测

    Electrochemical Catalyze Detection of L-Cysteine at Pt/Carbon Nanotube Electrode

      摘要
    • 摘要: 以电化学沉积法将Pt纳米颗粒沉积在碳纳米管(CNTs)上,并用扫描电镜(SEM)和能量色散X射线谱(EDS)对Pt/CNTs进行了表征.循环伏安图表明Pt/CNTs电极对L-半胱氨酸的电催化效果比石墨、Pt/石墨要好.同时,计时电流曲线表明Pt/CNTs电极对L-半胱氨酸在0.5~100.0μmol.L-1范围内有线性响应,其检测限为0.3μmol.L-1.
