Preparation and characterization of PtAu hybrid film modified electrodes and their use in simultaneous determination of dopamine, ascorbic acid and uric acid.

本文通过循环伏安电沉积法，在玻碳电极表面制备了由铂颗粒、金纳米颗粒（nanoAu）和L-半胱氨酸组成的PtAu混合膜修饰电极。SEM、AFM和XRD表明nanoAu粒径为50–80 nm，Pt粒径为200–300 nm；该混合膜也可沉积于金电极和透明ITO电极，用于电化学石英晶体微天平（EQCM）、扫描电镜、原子力显微镜、X射线衍射...
