Atomically precise gold nanoclusters (Au NCs) have high specific surface area and abundant unsaturated active sites. Traditionally, Au NCs are employed as thermocatalysts for multielectron transfer redox catalysis. Meanwhile, Au NCs also exhibit discrete energy levels, tunable photophysical and electrochemical properties, including visible to near infrared absorption, microsecond long-lived excited-state lifetime, and redox chemistry. In recent years, Au NCs are increasingly employed as visible to near infrared photocatalysts for their high photocatalytic activity and unique selectivity. This review focuses on the photophysical properties of a variety of Au NCs and their employment as photocatalysts in photocatalytic reactions and related applications including solar energy conversion and photodynamic therapies.
原子精确的金纳米团簇（Au NCs）具有高比表面积和丰富的不饱和活性位点。传统上，Au NCs被用作多电子转移氧化还原催化的热催化剂。同时，Au NCs还表现出离散的能级、可调的光物理和电化学性质，包括可见到近红外吸收、微秒级长寿命激发态寿命以及氧化还原化学性质。近年来，Au NCs因其高光催化活性和独特的选择性而越来越多地被用作可见到近红外光催化剂。本文综述了各种Au NCs的光物理性质及其在光催化反应以及包括太阳能转换和光动力疗法在内的相关应用中作为光催化剂的应用情况。
