Fuel cell research has been expanding in recent years as the demand for alternative fuels increases. Better catalysts 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. As a catalyst based on non-Pt to reduce Pt usage, in this presentation, we demonstrate the synthesis and characterization of bimetallic Au-Pd nanocomposite. Bimetallic Au-Pd catalysts are prepared with the use of ascrorbic acid as reductant at the various ratios of Au and Pd precursors. The structures and electrocatalytic activities of the bimetallic Au-Pd catalysts are characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), cyclic voltammetry (CV), and rotating disk electrode (RDE) voltammetry. This research was supported by Mid-career Researcher Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology (2011-0015619).
