摘要：Monodispersed mixtures of 6-nm Cu and Ag nanoparticles were prepared by electrochemical reduction on electrochemically polymerized poly -Fe(vbpy)3(PF6)2 film electrodes on glassy carbon. Conversion of the complex to poly -Fe(vbpy)2(CN)2 followed by surface binding of salts of the cations and electrochemical reduction gave a mixture of chemically distinct clusters on the surface, (Cu) m ,(Ag) n |polymer|glassy carbon electrode (GCE), as shown by X-ray photoelectron spectroscopy (XPS) measurements. A (Cu)2,(Ag)3|(80-monolayer- poly -Fe(vbpy)32+|GCE electrode at −1.33 V vs. reversible hydrogen electrode (RHE) in 0.5 M KHCO3, with 8 ppm added benzotriazole (BTA) at 0 °C, gave acetate with a faradaic efficiency of 21.2%.
