Development of low-Pt content cathode electrocatalyst in fuel cell has been recognized recently as one of the most important issues due to its high cost and limited supply. In particular, some approach to minimize the Pt content of electrodes has focused on the formation of small nanoparticles. In this presentation, we demonstrate a facile wet chemical strategy for preparing Pd based nanochain networks (PdNNs) and Pt decorated PdNN (Pt-on-PdNNs). The PdNNs were synthesized by simply mixing PdCl2 aqueous solution and poly(vinylpyrrolidone) (PVP) at pH = 7, followed by hydrazine hydrate reduction. For Pt-on-PdNNs, Pt was deposited spontaneously on the surface of the PdNNs. The prepared Pd based nanocatalysts, especially the Pt-on-PdNNs decorated with a very low amount of Pt, exhibited significant electrocatalytic activity and stability for the oxygen reduction reaction (ORR). This research was supported by the Daegu University Research Grant, 2012.
