Synthesis of carbon supported palladium particles based on a polyol process was investigated. The activity of Pd catalysts, synthesized by microwave assisted polyol method on carbon support, has been examined for formic acid electro-oxidation reaction. The catalysts were characterized with XRD to identify their nanostructure properties. The effect of catalyst preparation parameters on electrocatalytic performance of catalysts was examined. The electrocatalytic properties of Pd/C catalysts for the oxidation of formic acid were investigated by cyclic voltammetry (CV). The electrocatalytic activity of Pd/C synthesized at 30 s and 130 oC are higher than the other Pd/C catalysts synthesized at different temperature and reaction time. It is proposed that the longer reaction time and higher temperature increased the particle size.
Keywords: Formic acid electro-oxidation, Palladium catalysts, polyol method, preparation conditions, fuel cells.
