In the non-aqueous solution and recurring to the confocal Raman 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 CO, the oxidized product of HCOOH, was produced first. As the potential moves to positive, the first oxidation wave for CO 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.
在非水溶液中,借助共焦拉曼系统,作者利用表面增强拉曼光谱(SERS)研究了甲酸在铂电极表面的催化和氧化。结果表明,HCOOH的氧化产物中间体CO首先生成。随着电位向正向移动,在0.1V以上观察到CO的第一个氧化波。因此,CO的产物抵消了其消耗,所以在一定覆盖度下拉曼强度和耦合并未降低。随着CO氧化的加快,在0.6V时检测到最终氧化产物CO2。
