摘要：

Methanol oxidation reaction (MOR) has been studied on the low index planes of Pd (Pd(111), Pd(100) and Pd(110)) in 0.1 M HClO4 using voltammogram. Onset potential of methanol oxidation increases as Pd(110)similar to Pd(100) < Pd(111). The activity for the MOR is estimated using anodic peak current density of the voltammograms. The order of the activity is Pd(111)similar to Pd(110) << Pd(100): (100) surface enhances the activity for the MOR on Pd electrodes. (C) The Electrochemical Society of Japan, All rights reserved.
