在电化学研究中,共吸附是一种普遍而又很复杂的界面现象,参与共吸附的各物种之间以及它们与表面之间的作用在不同体系中有着本质上的不同。用常规电化学手段难以对共吸附行为进行详细分析,本文表明应用表面增强拉曼光谱(SERS)技术分析在这些体系中的SERS谱图同电化学参数的关系可以对共吸附现象作更深入的描述和分类。从Ag电极上获得SERS结果来看,可以分为两大类型的共吸附体系。
In electrochemical studies, co-adsorption is a common and complex phenomenon of interfacial phenomena. The interactions among the species involved in co-adsorption and their interaction with the surface are fundamentally different in different systems. It is difficult to conduct a detailed analysis of the co-adsorption behavior by conventional electrochemical methods. This paper shows that the SERS spectra of these systems in relation to electrochemical parameters can be further analyzed using surface enhanced Raman spectroscopy (SERS) Description and classification. SERS results obtained from the Ag electrode point of view, can be divided into two types of co-adsorption system.
