dc.description.abstract | This paper reports the synthesis and characterization of one dimensional nanocomposites composed of Ag, Au, and AgCl (denoted as Ag/Au/AgCl). The Ag/Au/AgCl composites with different compositional ratios are prepared by the galvanic replacement reaction between a Ag nanowire template and Au precursor at various concentrations (1, 10, 100 mM HAuCl 4). As the Au precursor concentration increases, the structure of the resulting Ag/Au/AgCl changes from a core-shell solid wire to a porous hollow wire with a decrease in the Ag and AgCl contents and increase in the Au content. The catalytic activity of Ag/Au/AgCl for the oxygen reduction reaction (ORR) is investigated in 0.1 M NaOH solution. The nanocomposite with a Ag:Au:AgCl compositional ratio of 4:86:10 shows reasonable ORR activity (high ORR current, positive onset potential) along with sufficient stability and ethanol tolerance in alkaline media, suggesting that it could be used as a substitute for Pt-based cathode catalysts in fuel cells.
