| 摘 要： | 本文应用时间分辨表面增强拉曼光谱（ＴＲＳＥＲＳ）结合电位阶跃和电位扫描的方法，研究了硫脲和ＣｌＯ－４在Ａｇ电极表面的共吸附层结构。结果表明ＳＥＲＳ谱峰强度随电极电位的响应速率与电位阶跃扫描的方向有关，ＴＵ和ＣｌＯ－４在Ａｇ表面的共吸附层在不同的电位下存在两种不同的构型，并且两种构型之间转化的难易程度不同。

| Abstract: | Time resolved Surface enhanced Raman Spectroscopy(TRSERS) has been combined with the potential step and scan method to study the structure of the coadsorption layer of thiourea and ClO - 4 at Ag electrodes. The SERS intensity versus time profiles show that the response rate of the SERS intensity to potential depends on the size of the step and on the scanning direction. The results also show that the coadsorption layer has two distinct structures at different potentials. The degree of the difficulty of mutual transformation is different between the two structures. |
