放氧反应是人工光合作用的关键步骤，具有很大的过电位。在半导体光催化剂中，可用于反应的光通常限于波长短于半导体吸收边的UV或可见光。另一方面，基于金纳米颗粒（Au NP）的等离子体光催化剂，特别是热电子转移（HET）型等离子体光催化剂，具有利用构成大部分太阳光的可见光至近红外光作为能量向上反应的驱动力的能力。近年来，对由Au纳米颗粒和半导体组成的HET型等离子体光催化剂的实验和理论研究一直在进行。本文重点介绍了Au NP基等离子体光催化剂的基本原理和最新进展。在介绍之后，首先处理等离子体激元光催化剂的合理设计的基础。其次，按照半导体、Au NPs和它们的界面的顺序处理等离子体光催化剂的具体设计。第三，介绍了近年来等离子体光催化剂的研究进展。最后，对本文的研究工作进行了总结，并对等离子体光催化剂的研究方向进行了展望。
The oxygen evolution reaction (OER) with a large overpotential is the key step common to artificial photosynthesis. In semiconductor photocatalysts, the light available to the reactions is usually limited to UV or visible with wavelengths shorter than the absorption edge of the semiconductors. On the other hand, gold nanoparticle (Au NP)-based plasmonic photocatalysts, particularly hot-electron transfer (HET)-type plasmonic photocatalysts, have the capability to utilize visible-to-near infrared light that makes up most sunlight as a driving force for the energetically uphill reactions. In recent years, experimental and theoretical studies on HET-type plasmonic photocatalysts consisting of Au NPs and a semiconductor have been intensively pursued. This perspective article highlights the fundamentals and recent progress of Au NP-based HET-type plasmonic photocatalysts for OER. After the introduction, the basics for the rational design of plasmonic photocatalysts are treated first. Secondly, the concrete design for the plasmonic photocatalysts is dealt with in the order of semiconductors, Au NPs, and their interface. Thirdly, recent advanced studies on plasmonic photocatalysts for OER are described. Finally, the conclusions are summarized with a direction for future research on plasmonic photocatalysts.
