Key Structural Factors of Group 5 Metal Oxide Clusters for Base Catalytic Application

Part of the book series: Springer Theses ((Springer Theses))

Abstract

In this chapter, the structural and catalytic properties of metal oxide clusters [MxOy]n− (M: metal), called polyoxometalates (POMs), are summarized. POMs have been applied as catalysts for acid/base-catalyzed, oxidation, photocatalytic, and electrochemical reactions by exploiting their controllable geometric structures and tunable chemical properties. Because POMs have atomically precise structures, a combination of experimental and theoretical studies has provided an understanding of how POMs function as catalysts and the key structural factors for catalysis. This chapter summarizes the previous work on the structural diversity of POMs, especially group 5 POMs, with a focus on the origin of their unique catalytic properties for acid/base-catalyzed and oxidation reactions. Finally, based on the trade-off between the stability and basicity of POM clusters, the possibility of using group 5 elements as the constituent metals of POMs for base catalytic applications is discussed.
