Utilizing plasmon-generated hot carriers to drive chemical reactions has emerged as a popular topic in solar photocatalysis. However, a complete description of the underlying mechanism of hot-carrier transfer in photochemical processes remains elusive, particularly for those involving hot holes. Photoelectrochemistry enables to localize hot holes on photoanodes and hot electrons on photocathodes and thus offers an approach to separately explore the hole-transfer dynamics and electron-transfer dynamics. This review summarizes a comprehensive understanding of both hot-hole and hot-electron transfers from photoelectrochemical studies on plasmonic electrodes. Additionally, working principles and applications of spectroelectrochemistry are discussed for plasmonic materials. It is concluded that photoelectrochemistry provides a powerful toolbox to gain mechanistic insights into plasmonic photocatalysis.

等离子光电化学：热载流子

利用等离子体产生的热载流子驱动化学反应已成为太阳能光催化领域的热门话题。然而，对光化学过程中热载流子转移的潜在机制的完整描述仍然难以捉摸，特别是对于那些涉及热孔的过程。光电化学能够定位光阳极上的热空穴和光阴极上的热电子，因此提供了一种分别探索空穴转移动力学和电子转移动力学的方法。这篇综述总结了对等离子体电极光电化学研究中热空穴和热电子转移的全面理解。此外，还讨论了等离子体材料的光谱电化学的工作原理和应用。
