摘　　要：A simple method for the preparation of Pd nanoparticles is described. The Pd nanoparticles were electrodeposited on the gold electrode surface from 0.5 mol/L H 2SO 4 solution containing 0.01 mol/L K 2PdCl 4 by applying potential step from 1.1 V to 0 V through 5 s. 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 0.1 mol/L KCl solution.A simple method for the preparation of Pd nanoparticles is described.
