　　报告简介：

　　“Strong Metal Support Interaction”(SMSI) was discovered 40 years ago by Tauster. It had a strong impact on the development of heterogeneous catalysis of supported metal in convincing researchers in the intimate interactions and active role of the catalyst support. The classical SMSI phenomenon is associated with reductive treatment of group VIII metals on many oxides such as TiO2. After 2000, supported nanogold catalysts attracted much of community’s interests. Although support effects on the gold catalysts were soon realized, for long time there had not been any report of symptom(encapsulation and electron transfer between metal and support) of SMSI similar to the ones discussed by Tauster. In 2012, Xiaoyan Liu et al discovered the first case of SMSI in gold catalyst with signature evidence of reversible encapsulating Au by the ZnO support. Surprisingly, SMSI in this case was induced by oxidative treatment instead of reductive as in classical SMSI. The direction of electron transfer is also opposite to that of classical SMSI. This new type of oxidative SMSI impacted on catalysis showing not only better sinter-resistance property but also better oxygen activation. In this lecture I will discuss the recent developments from my laboratory on this puzzling new phenomenon. It was concluded that oxidative SMSI establish new bonding interactions between Au and oxygen in the defective lattice of ZnO support. These interacting oxygen atoms are active in a Mars van Krevelin mechanism of oxygen activation and participation in catalytic oxidation of CO.
