We summarize here the research advances on the reactivity of metal clusters. After a simple introduction of apparatuses used for gas-phase cluster reactions, we focus on the reactivity of metal clusters with various polar and nonpolar molecules in the gas phase and illustrate how elementary reactions of metal clusters proceed one-step at a time under a combination of geometric and electronic reorganization. The topics discussed in this study include chemical adsorption, addition reaction, cleavage of chemical bonds, etching effect, spin effect, the harpoon mechanism, and the complementary active sites (CAS) mechanism, among others. Insights into the reactivity of metal clusters not only facilitate a better understanding of the fundamentals in condensed-phase chemistry but also provide a way to dissect the stability and reactivity of monolayer-protected clusters synthesized via wet chemistry.
我们在这里总结了金属团簇反应性的研究进展。在简单介绍了用于气相团簇反应的仪器之后，我们重点研究了气相中各种极性和非极性分子与金属团簇的反应性，并说明了金属团簇在几何和电子重排的共同作用下，如何逐步进行基元反应。本研究讨论的主题包括化学吸附、加成反应、化学键的断裂、刻蚀效应、自旋效应、鱼叉机制和互补活性位（CAS）机制等。对金属团簇反应性的深入了解不仅有助于更好地理解凝聚相化学的基础，而且还为通过湿化学合成的单层保护团簇的稳定性和反应性提供了一种剖析方法。
