英文摘要	随着纳米科学的发展，人们再次关注到金属电极上的光电化学研究. 这主要得益于币族金属纳米结构具有强的表面等离激元共振（SPR）效应，它能有效地将光从远场光转化为近场光，汇聚光能到金属表面区域，可以在表面产生强的光电场效应，或产生较长寿命的热电子-空穴载流子效应，或是更长时间尺度的热效应. 因此，SPR效应不仅产生了表面增强拉曼散射(SERS)效应，用于表征吸附分子，而且可能诱发表面化学反应，为在电化学界面实现光与电协同调控化学反应提供新思路. 本文首先回顾了金属电极上光电流理论的发展，然后总结了本研究组近年来将量子化学计算用于光电化学反应和SERS光谱研究的工作，并以在银金纳米结构电极上水合质子还原和芳香胺氧化为例，比较了热电子和热空穴参与光电化学反应的特点，揭示了SPR参与光电化学反应的本质.; At present photoelectrochemistry has received much concern back to nanostructures of noble metals from semiconductor electrodes. This is due to the surface plasmon resonance (SPR) effect of metallic nanostructures, which can effectively convert the far-field light to the near-field light and concentrate the photonic energy to the local surface area with high energy density. Thus, the different enhancement mechanisms, such as the local optical field enhancement, the formation of light generated hot carriers (hot electron-hole pairs), or the photothermal effect, have been proposed in literatures. On the basis of the SPR enhancement effect, the surface-enhanced Raman spectroscopy (SERS) can be used to characterize the surface species but also induce surface chemical reactions. This provides a new idea to study the synergic effect of light and electricity in electrochemical interfaces. The article first reviewed a brief history of photoelectrochemistry, and then summarized our work on the light splitting water to hydrogen molecules, the photo-driven surface catalytic coupling reactions of the p-aminothiophenol oxidation and the p-nitrothiophenol reduction in electrochemical interfaces. Finally, we presented a simple prospective on the relationship of the SPR and the hot electron-hole pairs to plasmon-enhanced photoelectrochemical reactions.; 国家自然科学基金（No. 21321062, No. 21533006和No. 21373712）、科技部973课题（No. 2015CB932303）以及厦门大学化学化工学院固体表面物理化学国家重点实验室的自主课题资助.; 作者联系地址：厦门大学化学化工学院化学系，固体表面化学国家重点实验室，福建厦门361005; Author's Address: Department of Chemistry，College of Chemistry and Chemical Engineering, State Key Laboratory of Physical Chemistry of Solid Surfaces, Xiamen University, Xiamen 361005, Fujian, China; 通讯作者E-mail：dywu@xmu.edu.cn
