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.
Many energy and life-related processes strongly rely on the structure and properties of the electrochemically charged interface and have been rapidly applied to the in-situ study of electrochemical interfaces since the surface-enhanced Raman spectroscopy was discovered, The level and depth of the various surface (or interface) structure and process characterization, such as the identification of species in the surface bonding, configuration and orientation, etc. In the recent decade, the rapid development of nanotechnology for SERS technology provides a rich substrate and detection And characterization methods, which promoted the remarkable development of electrochemical SERS field which is closely related to nanoscience.In this paper, the SERS, SERS, SERS, SERS, core-shell structure SERS of Au and Ag are systematically introduced, Gap-modeSERS, TERS and SHINERS, which are used in the study of single crystal surface, are interspersed with the historical development, current situation, existing problems and prospects of electrochemical SERS, and provide a comprehensive and detailed reference for electrochemical SERS research.
