Different from isolated metal atoms and large metal nanoparticles (NPs), supported metal clusters (SMCs) possess distinct geometric and electronic structures and thus exhibit enhanced activity and designated selectivity in catalysis. So far, with the development in synthetic methodologies and characterization techniques, SMCs with fine structures could be constructed and well-defined at the atomic level. In addition, based on computational modeling of SMCs, theoretical calculations corroborated well with experimental results, providing in-depth insights into the structure–property relationship for SMCs in catalysis. In this Review, classic synthetic strategies and key characterization techniques of SMCs are summarized. Subsequently, the applications of SMCs in important catalytic reactions based on recent studies are discussed, including aerobic oxidation, hydrogenation, dehydrogenation, water–gas shift (WGS) reaction, and photocatalytic reactions. In particular, the importance of the cluster size-effect and metal–support interactions in determining the catalytic performance of SMCs is highlighted. Lastly, challenges and prospects in SMCs’ catalysis are illustrated.

支持的金属团簇:异相催化的制备与应用
与孤立的金属原子和大型金属纳米粒子(NP)不同,负载型金属簇(SMC)具有独特的几何和电子结构,因此在催化中表现出增强的活性和指定的选择性。到目前为止,随着合成方法学和表征技术的发展,具有精细结构的SMC可以在原子水平上得到构建和明确定义。此外,基于SMC的计算模型,理论计算与实验结果很好地吻合,为深入了解SMC在催化中的结构与性质之间的关系提供了深入的见解。在这篇综述中,总结了SMC的经典合成策略和关键表征技术。随后,基于最近的研究,讨论了SMC在重要催化反应中的应用,包括有氧氧化,加氢,脱氢,水煤气变换(WGS)反应和光催化反应。尤其要强调的是,团簇尺寸效应和金属-载体相互作用在确定SMC催化性能中的重要性。最后,阐述了SMCs催化的挑战和前景。
