Improving the knowledge of the relationship between structure and properties is fundamental in catalysis. Recently, researchers have developed a variety of well-controlled methods to synthesize atomically precise metal nanoclusters (NCs). NCs have shown high catalytic activity and unique selectivity in many catalytic reactions, which are related to their ultrasmall size, abundant unsaturated active sites, and unique electronic structure different from that of traditional nanoparticles (NPs). More importantly, because of their definite structure and monodispersity, they are used as model catalysts to reveal the correlation between catalyst performance and structure at the atomic scale. Therefore, this review aims to summarize the recent progress on NCs in catalysis and provide potential theoretical guidance for the rational design of high-performance catalysts. First a brief summary of the synthetic strategies and characterization methods of NCs is provided. Then the primary focus of this review-the model catalyst role of NCs in catalysis-is illustrated from theoretical and experimental perspectives, particularly in electrocatalysis, photocatalysis, photoelectric conversion, and catalysis of organic reactions. Finally, the main challenges and opportunities are examined for a deep understanding of the key catalytic steps with the goal of expanding the catalytic application range of NCs.

原子精确的贵金属纳米簇作为高效催化剂:结构与性能之间的桥梁。

增进对结构与性质之间关系的认识是催化的基础。最近,研究人员开发了各种控制良好的方法来合成原子精确的金属纳米团簇(NCs)。NCs在许多催化反应中均显示出高催化活性和独特的选择性,这与它们的超小尺寸,丰富的不饱和活性位点以及与传统纳米颗粒(NPs)不同的独特电子结构有关。更重要的是,由于其确定的结构和单分散性,它们被用作模型催化剂,以揭示原子尺度上催化剂性能与结构之间的相关性。所以,这篇综述旨在总结NCs在催化领域的最新进展,并为合理设计高性能催化剂提供潜在的理论指导。首先简要介绍了NC的合成策略和表征方法。然后从理论和实验的角度说明了本综述的主要重点-NC在催化中的模型催化剂作用-尤其是在电催化,光催化,光电转换和有机反应催化方面。最后,考察了主要挑战和机遇,以深入了解关键的催化步骤,目的是扩大NC的催化应用范围。然后从理论和实验的角度说明了本综述的主要重点-NC在催化中的模型催化剂作用-尤其是在电催化,光催化,光电转换和有机反应催化方面。最后,考察了主要挑战和机遇,以深入了解关键的催化步骤,目的是扩大NC的催化应用范围。然后从理论和实验的角度说明了本综述的主要重点-NC在催化中的模型催化剂作用-尤其是在电催化,光催化,光电转换和有机反应催化方面。最后,考察了主要挑战和机遇,以深入了解关键的催化步骤,目的是扩大NC的催化应用范围。
