Nanobimetallic particles of Au-Pt alloy were synthesized by reducing HAuCl 4 and H 2 PtCl 4 mixture solution with NaBH 4 . UV-Vis spectra, transmission electron microscopy (TEM), and X-ray diffraction (XRD) results revealed that the alloy was single phase with face-centered cube structure. The Au-PtZCysteine/glassy carbon electrode was prepared by self-assembling nanobimetallic particles on glassy carbon substrate modified with cysteine and was characterized with scanning electron microscopy (SEM). The average diameter of the particles was 12.6 nm. The electrochemical performance of Au-Pt/Cysteine/glassy carbon electrode was studied by cyclic voltammetry method. The result showed that the electrode of Au-Pt/Cysteine/ glassy-carbon had good electrocatalytic activity for methanol oxidation.
