Fuel cell has attracted much attention in recent years as a new energy system. Better electrocatalysts for oxygen reduction reaction (ORR) are needed to improve the efficiency and to lower the cost of fuel cells. Pt and its alloys are still the best electrocatalysts for ORR, but the high cost and limited supply of Pt are the problem. Metal nanowires have been studied extensively because of their potential use as active components of electronic, photonic, and sensing devices. This presentation reports the synthesis and characterization of one dimensional nanocomposites composed of Ag and Au (denoted Ag/Au). Ag/Au nanocomposites are prepared by galvanic replacement reaction between Ag nanowires and Au precursor at various concentrations (1, 10, and 100 mM HAuCl4). The structures, morphologies and electrocatalytic activities of these nanomaterials are characterized by scanning electron microscopy (SEM), rotating disk electrode (RDE) and cyclic volatammetry (CV). This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology (2011-0005623).
