This paper describes an effective route to synthesize gold-platinum bimetallic( Au-Pt) by a controllable electrodeposition method induced by a self-assembled cysteamine( Cys) monolayer on the surface of a glass carbon electrode( GCE). The Au-Pt / Cys / GCE electrodes were characterized by field emission scanning electron microscopy( FE-SEM) and investigated by cyclic voltammetry( CV). The morphologies of bimetallic depended on the electrodeposition time and potential. The results showed that Au-Pt / Cys / G...
