一、引言单纯的电化学测量技术仅能获得电极/溶液界面结构和反应历程的间接信息,近三十年来发展起来的光谱电化学技术可在电化学过程发生的同时对电极/溶液界面的结构和过程进行光谱现场观察,从而为在分子水平认识这些问题提供直接依据。光谱技术和电化学方法的密切结合有许多优点。电化学方法具有可控制体系的物质状态、能定量产生反应物种等优点。而光谱技术则在鉴 I. INTRODUCTION Simple electrochemical measurement technology can only obtain the indirect information of the electrode / solution interface structure and reaction process. The development of the spectroscopic electrochemical technique in recent thirty years can make the structure of the electrode / solution interface And the process of field observations on the spectrum, thus providing a direct basis for understanding these issues at the molecular level. The close combination of spectroscopy and electrochemical methods has many advantages. The electrochemical method has the advantages of controlling the state of the substance of the system and producing the reaction species quantitatively. The spectroscopy is in the study
