摘要

Apolyol process is employed to synthesize Pd nanoparticles supported on carbon (Pd/C), fordeveloping an electrocatalyst with excellent performance for methanol oxidation. The results show thatthis method has a high efficiency for the Pd nanoparticles depositing on the carbon support. Moreover,the average diameter of the Pd nanoparticles decreases with the amount of KOH solution employedduring the catalyst synthesis. The highest electrochemical activity of the Pd/C catalyst for the methanoloxidation in 0.1 M KOH solution with 1.0 M methanol at 25o C reaches to 447.4 mA mg -1 Pd. Theactivity difference between the Pd/C catalysts prepared at 200 (447.4 mA mg -1 Pd) and 180 o C (435.8mA mg -1 Pd) for the methanol electrooxidation is very small, showing that the polyol process issuitable for the preparation of the Pd/C.
