Abstract: Asimple method for the preparation of Pd nanoparticleSIs described.The Pd nanoparticles were electrodeposited on the gold electrode surface from 0.5 mol/L H2SO4solution containing 0.01mol/L K2PdCl4by applying potential step from 1.1 Vto 0 Vthrough 5s.Scanning electron microscopy proved that the as-prepared Pd nanoparticles are uniformly distributed on the bare gold electrode surface.The resulted Pd nanoparticles film modified gold electrode possesses a high catalytic activity for the reduction of dissolved oxygen in 0.1mol/L KCl solution.

Key words: Gold electrode, Pd nanoparticles, Electrocatalysis, Oxygen reduction
