Plasmonic nanomaterials can convert low-intensity solar energy into chemical energy due to their surface plasmon resonance (SPR) effect, offering an interesting approach to enhancing solar energy conversion efficiency. Unraveling the physicochemical mechanisms of hot carrier relaxation and precise design of hybrid plasmonic nanostructures are crucial for optimizing the potential of the SPR effect in photocatalysis, especially considering the ongoing challenges of low quantum efficiency and controversial mechanisms in plasmon-enhanced reactions. Characterization and analysis methods at the single-particle level are emerging as powerful tools for achieving this objective. It can reveal adsorbate–surface interactions, determine reliable structure–activity relationships of individual nanoparticles, and further analyze potential catalytic mechanisms. In this review, we highlighted the progression of catalytic mechanism studies at the single-particle level that include the exploration of interfacial charge transfer between SPR nanoparticles with an adsorber (metal, semiconductors, or molecule), imaging chemical activity, and the evolution of nanostructures, which provided guidance to design highly efficient hybrid plasmonic nanomaterials. Finally, we discuss future challenges and prospects in the field. This review aims to offer insights into plasmonic photocatalysis by emphasizing catalytic mechanism studies at the single-particle level, with the goal of expediting the development of high-performing plasmonic photocatalysts.

混合等离子体纳米材料的光催化:从单颗粒水平的催化机制研究到材料设计



等离子体纳米材料由于其表面等离子体共振(SPR)效应,可以将低强度太阳能转化为化学能,为提高太阳能转换效率提供了一种有趣的方法。揭示热载流子弛豫的物理化学机制和混合等离子体纳米结构的精确设计对于优化SPR效应在光催化中的潜力至关重要,特别是考虑到低量子效率和等离子体增强反应中有争议的机制的持续挑战。单颗粒水平的表征和分析方法正在成为实现这一目标的强大工具。它可以揭示吸附物-表面相互作用,确定单个纳米粒子的可靠结构-活性关系,并进一步分析潜在的催化机制。在这篇综述中,我们重点介绍了单粒子水平催化机制研究的进展,包括探索 SPR 纳米粒子与吸附剂(金属、半导体或分子)之间的界面电荷转移、成像化学活性以及纳米结构的演化,为设计高效混合等离子体纳米材料提供了指导。最后,我们讨论了该领域未来的挑战和前景。本综述旨在通过强调单颗粒水平的催化机制研究来深入了解等离子体光催化,以加快高性能等离子体光催化剂的开发。
