摘要：
Keywords: Nanocrystals; Clusters; Isolated Single Atomic Catalysis(ISAC) Metallic nanocrystals, clusters, and isolated single atom sites(ISAS) are important catalysts that have been widely used in both heterogeneous and homogeneous catalysis. It is of great significance to understand the essence and laws of catalysis for the frontier of chemistry and chemical engineering. More and more attention has been paid to the correlation of catalyst structure and catalytic properties. To date, researchers have uncovered many important factors governing the catalytic performance of nano, cluster, and single atom catalysts, including composition, shape, size, surface/interface effects and so on. However, challenges remain in the following aspects: intrinsically what the active site or center of the catalyst is in heterogeneous catalysis; which is the key factor determining the catalytic performance: composition, structure (shape), size, interaction between catalyst and support, or surface/interface effects; whether or not the latest achievements of nanotechnology could be applied to the fundamental and applied research of catalysis, so as to improve the activity, selectivity and stability of the catalyst, and if so, how to manage; whether enzyme catalysts could be manufactured with high activity and specific selectivity in ambient conditions as enzyme in nature. Herein, we made some explorative attempts and achieved valuable results in combination with several catalysis in chemical engineering.
