Shedding insights into the acid-base properties at the atomic level is crucial for heterogeneous catalysis. How to detect and identify the geometric structure, exact position and the acid-base properties of active sites remains a tremendous challenge in heterogeneous catalysis. Recently, we find that the interfacial Lewis acid−base pair [Ru-O-Ce-Vö], which consists of acidic Ce-Vö site and basic interfacial oxygen of Ru-O-Ce linkage, is readily formed on the Ru-clusters/ceria. Based on this discovery, the concept “Interfacial Acid-Base Pair” is mentioned for the first time (J. Am. Chem. Soc.). Recently, we find that the quinazolinones can be synthesized from olefins, CO and amines over heterogeneous Ru-clusters/ceria catalyst, forming three new bonds including C-C, C-N and C=N. This work has been selected as “Hot Paper” and published in the journal of Angew. Chem. Int. Ed.
