Supported atomic clusters with uniform metal sites and definite low-nuclearity are intermediate states between single-atom catalysts (SACs) and nanoparticles in size. Benefiting from the presence of metal-metal bonds, supported atomic clusters can trigger synergistic effects among every metal atom, which contributes to achieving unique catalytic properties different from SACs and nanoparticles. However, the scalable and precise synthesis and atomic-level insights into the structure-properties relationship of supported atomic clusters is a great challenge. This perspective presents the latest progress of the synthesis of supported atomic clusters, highlights how the structure affects catalytic properties, and discusses the limitations as well as prospects.
具有均匀金属位点和确定低核数的负载型原子簇是尺寸介于单原子催化剂（SAC）和纳米颗粒之间的中间态。得益于金属-金属键的存在，负载型原子簇能够引发每个金属原子之间的协同效应，这有助于实现不同于SAC和纳米颗粒的独特催化性能。然而，负载型原子簇的可扩展精确合成以及对其结构-性能关系的原子水平洞察是一项巨大挑战。本文综述介绍了负载型原子簇合成的最新进展，突出了结构如何影响催化性能，并讨论了局限性和前景。
