Ultrasmall metal nanoparticles with the particle size less than 2 nm exhibit quantum-sized electronic structures and size-dependent reaction activities, and they are known as metal nanoclusters (NCs), which are quite different from the single atom and metal nanoparticles. Aerobic oxidation is a green pathway for CO oxidation, alcohol oxidation, hydrocarbon oxidation, photooxidation, and so on. The resistance to oxidation and sintering is required for the metal-based catalysts during the oxidation progresses. The investigation of active catalysts in aerobic oxidation has inspired a guiding route for the preparation of efficient metal NCs. This review introduces recent progresses of metal NCs in aerobic oxidation. We focus on the relationship of size and electronic property of the metal NC core and the stabilized ligand and support with catalytic oxidation. The correlation and the developed strategies in maintaining efficient oxidation can be beneficial for their applications in the industry.

粒径小于2 nm的超小型金属纳米颗粒表现出量子尺寸的电子结构和尺寸依赖的反应活性，它们被称为金属纳米簇（NCs），与单原子和金属纳米颗粒完全不同。有氧氧化是CO氧化，醇氧化，烃氧化，光氧化等的绿色途径。在氧化过程中，金属基催化剂需要抗氧化和烧结的性能。有氧氧化中活性催化剂的研究为制备高效金属NC提供了指导。这篇综述介绍了金属NCs在好氧氧化中的最新进展。我们专注于金属NC核与稳定配体和催化氧化载体的尺寸和电子性能之间的关系。保持有效氧化的相关性和已开发的策略对其在工业中的应用可能是有益的。
