Pd nanoparticles (NPs) were directly deposited on indium-tin oxide (ITO) electrodes by cyclic voltammetry (CV) in a bulk Pd2+ solution and the size of the Pd (NPs) was evaluated by SEM. The electrochemical deposition conditions of the Pd NPs were varied according to a scan rate. As the scan rate was decreased, the size of the Pd NPs increased, but the formic acid catalytic property was weakened. With regard to cycle number, with increased cycling, the size of the Pd NPs increased but the formic acid catalytic property decreased. As the conditions of electrochemical deposition were varied, the particle size and catalytic activity for formic acid were also changed. (C) 2010 Elsevier B.V. All rights reserved.
