Electrocatalysis plays a vital role in energy conversion and storage in modern society. Localized surface plasmon resonance (LSPR) is a highly attractive approach to enhance the electrocatalytic activity and selectivity with solar energy. LSPR excitation can induce the transfer of hot electrons and holes, electromagnetic field enhancement, lattice heating, resonant energy transfer and scattering, in turn boosting a variety of electrocatalytic reactions. Although the LSPR-mediated electrocatalysis has been investigated, the underlying mechanism has not been well explained. Moreover, the efficiency is strongly dependent on the structure and composition of plasmonic metals. In this review, the currently proposed mechanisms for plasmon-mediated electrocatalysis are introduced and the preparation methods to design supported plasmonic nanostructures and related electrodes are summarized. In addition, we focus on the characterization strategies used for verifying and differentiating LSPR mechanisms involved at the electrochemical interface. Following that are highlights of representative examples of direct plasmonic metal-driven and indirect plasmon-enhanced electrocatalytic reactions. Finally, this review concludes with a discussion on the remaining challenges and future opportunities for coupling LSPR with electrocatalysis.

用于增强电催化的局部表面等离子体共振

电催化在现代社会的能量转换和存储中起着至关重要的作用。局域表面等离子体共振 (LSPR) 是一种非常有吸引力的方法，可以提高太阳能的电催化活性和选择性。LSPR 激发可以诱导热电子和空穴的转移、电磁场增强、晶格加热、共振能量转移和散射，进而促进各种电催化反应。尽管已经研究了 LSPR 介导的电催化，但其潜在机制尚未得到很好的解释。此外，效率在很大程度上取决于等离子体金属的结构和组成。在这次审查中，介绍了目前提出的等离子体介导的电催化机制，并总结了设计支持的等离子体纳米结构和相关电极的制备方法。此外，我们专注于用于验证和区分电化学界面所涉及的 LSPR 机制的表征策略。接下来是直接等离子体金属驱动和间接等离子体增强电催化反应的代表性例子的亮点。最后，本综述最后讨论了 LSPR 与电催化耦合的剩余挑战和未来机遇。接下来是直接等离子体金属驱动和间接等离子体增强电催化反应的代表性例子的亮点。最后，本综述最后讨论了 LSPR 与电催化耦合的剩余挑战和未来机遇。接下来是直接等离子体金属驱动和间接等离子体增强电催化反应的代表性例子的亮点。最后，本综述最后讨论了 LSPR 与电催化耦合的剩余挑战和未来机遇。
