原位电化学拉曼光谱利用入射光诱导物质分子的散射现象，通过测定拉曼光谱信号与电极电位或电流强度的变化关系，来表征电极表面(界面)的分子微观结构。该技术能够获取电化学界面上的分子振动信息以及与化学反应相关的结构信息，并进行实时监测，因此在物质界面表征领域得到了广泛应用。本文从原位电化学拉曼光谱的原理出发，综合叙述了基于粗糙金属电极的原位电化学拉曼光谱在固-液界面分析的进展，包括分子吸附、析氧反应、析氢反应和氧还原反应;同时，探讨了界面结构、反应过程以及催化中间体与拉曼信号强度的关系，介绍了催化过程反应机理和催化物质的催化机理，最后，对下一阶段原位电化学拉曼光谱法在固-液界面分析中存在的科学问题进行展望。
Applications of in-situ electrochemical Raman spectroscopy based on rough metal electrodes in solid-liquid interface
In-situ electrochemical Raman spectroscopy measures the relationship between the Raman spectrum signal and the electrode's potential or current intensity,by utilizing the scattering phenomenon of the substance molecules induced by the incident light.It can provide molecular-level structural information about the electrode's surface(interface).This technology enables the acquisition of molecular vibrational information and real-time monitoring of structural information related to chemical reactions at the electrochemical interface,making it widely applicable in the field of material interface characterization.Starting from the principle of in-situ electrochemical Raman spectroscopy,this paper comprehensively describes the progress of in situ electrochemical Raman spectroscopy based on rough metal electrodes in solid-liquid interface analysis,such as molecular adsorption,oxygen evolution,hydrogen evolution,and oxygen reduction reaction.Furthermore,this paper explores the relationship between the interface structure,reaction processes,catalytic intermediates,and the Raman signal intensity.The catalytic process reaction mechanism and the catalytic mechanism of the catalytic material were presented.Lastly,an outlook was provided on the scientific challenges pertaining to in-situ electrochemical Raman spectroscopy at solid-liquid interfaces in the subsequent phase.
