中文摘要：

采用共焦显微拉曼系统研究了甲酸在非水体系中的纯多晶铂电极上的表面增强拉曼光谱，实验发现电位较低时甲酸首先在粗糙铂电极表面生成CO中间体，当电位逐渐变正并高于0．1V时CO开始氧化，但是此时新生成的CO足以弥补其氧化的消耗，表现在Raman强度和一定覆盖度下的耦合作用并没有减少。当电位达到约0．6V时CO的氧化速度进一步加剧并完全氧化为最终产物CO2。

英文摘要：

In the non-aqueous solution and recurring to the confocal Rarnan system, the authors studied the catalysis and oxidation of formic acid on the surface of platinum electrode utilizing surface-enhanced Raman spectroscopy （SERS）. Results showed that the intermediate CA）, the oxidized product of HCOOH, was produced first. As the potential moves to positive, the first oxidation wave for （X） is observed over 0.1 V. As a result the product of CO counteracts its consumeption, so the Raman intensity and coupling under the certain overlay was not decreased. As the oxidation of CO was expedited, the finally oxidized product CO2 was detected at 0.6 V.
