摘　　要：许多和能源、生命相关的过程都强烈依赖于电化学荷电界面的结构和性能.自从表面增强拉曼光谱效应发现后,就很快地被应用于电化学界面的原位研究,即从分子水平上深入表征各种表面(或界面)的结构和过程,如鉴别物种在表面的键合、构型和取向等.最近十年,纳米科技的飞速发展为SERS技术提供了丰富的基底以及检测和表征方法,从而推动了与纳米科学密切相关的电化学SERS领域令人瞩目的发展.本文系统介绍Au和Ag的SERS、过渡金属薄层SERS、纯过渡金属SERS、核壳结构SERS和已经可以应用于单晶表面研究的gap-modeSERS、TERS和SHINERS,其中穿插着介绍电化学SERS的历史发展、现状和存在的问题及其展望,为电化学SERS研究提供较为全面的详细的参考.Electrochemical interface is a very important interface closely related to various energy and life processes. Surface-enhanced Raman scattering was widely used in electrochemistry soon after its discovery to understand the surface bonding,configuration,and orientation of the surface species. In recent 10 years,the fast development of nanoscience and nanotechnology has offered SERS with abundant substrates and characterization methods,which has allowed impressive development of electrochemical SERS. This articles will follow the time line to make systematically overview of SERS on Au and Ag,thin-layer transition-metal SERS,pure transition metal SERS,core-shell SERS and those methods for studying single crystal surfaces,including gap-mode SERS, TERS and SHINERS. Emphasis will be put on the history,present status and existing problems and perspectives of electrochemical SERS. We hope the present article will provide a comprehensive overview of the electrochemical SERS.
