| 摘 要： | 采用电化学、ＸＰＳ和拉曼光谱研究钯微粒修饰聚苯胺（ＰＡＮ（Ｐｄ）电极对甲酸氧化的电催化行为。由于钯与ＰＡＮ的相互作用，钯微粒在所研究的电位区间可稳定地固定于ＰＡＮ中，且甲酸在钯上的氧化明显地抑制ＰＡＮ的氧化降解，使ＰＡＮ（Ｐｄ）电极电催化甲酸氧化反应具有高的稳定性和活性。

| Abstract: | Electrochemical oxidation of formic acid at polyaniline films modified by palladium microparticles (PAN(Pd)) has been studied using electrochemical techniques,XPS and Raman spectroscopy. It has been shown that because of the interaction between Pd and PAN, Pd microparticles can be stablized in the PAN films in the potential region from -0.2V to +0.9V, and the oxidation of formic acid can prevent the degradation of the PAN, resulting in high stability of the PAN(Pd) electrode and its electrocatalytic activity for oxidation of formic acid. |
