The sun offers a clean and renewable energy cornucopia, whereas how to utilize this inexhaustible yet decentralized energy with the assistance of appropriate media is an enduring topic. Plasmonic metal-based nanostructures (mainly Au and Ag) represent a class of fascinating materials for solar energy conversion due to their exclusive surface plasmon resonance (SPR)-enabled light-harvesting capability. In contrast to these plasmonic metals with characteristic SPR peaks, modulating the optical absorption peaks of nonplasmonic metals (e.g., small Pt nanoparticles) in the visible region but without size alteration is a grand challenge. Until recently, we demonstrated a near field scattering (NFS) optical model to manipulate the absorption peaks of Pt nanoparticles by adjusting their dielectric environment, sowing the seeds for tuning the optical absorption property of other metal nanoparticles and even semiconductor quantum dots. It is the purpose of the present Perspective to retrospect the history of NFS optical model and guide the function-oriented design of NFS-based nanostructures for artificial photoredox transformation.

基于近场散射光学模型的催化剂设计用于人工光氧化还原转化

太阳提供了清洁和可再生能源的聚宝盆，而如何借助适当的媒体来利用这种取之不尽但分散的能源是一个经久不衰的话题。基于等离子体金属的纳米结构（主要是 Au 和 Ag）由于其独特的表面等离子体共振 (SPR) 光捕获能力，代表了一类用于太阳能转换的迷人材料。与这些具有特征 SPR 峰的等离子体金属相比，在可见区域调制非等离子体金属（例如，小的 Pt 纳米粒子）的光吸收峰但不改变尺寸是一个巨大的挑战。直到最近，我们展示了一种近场散射 (NFS) 光学模型，通过调整 Pt 纳米粒子的介电环境来控制其吸收峰，为调整其他金属纳米粒子甚至半导体量子点的光吸收特性播下种子。本展望的目的是回顾 NFS 光学模型的历史，并指导基于 NFS 的纳米结构的功能导向设计，用于人工光氧化还原转化。
