Heterometallic Polyoxotungstate Nanocluster and Their Applications

Abstract

Polyoxometalates are self-assembled metal-oxygen nanoclusters with diverse structural properties. These consist of early transition metals such as tungsten, molybdenum, niobium, vanadium, etc. in their highest oxidation states. The synthesis of heterometallic polyoxometalates was an incipient field a decade ago due to the difficulties in the synthesis. However, various methods have been discovered to synthesise these compounds, and exploration of varieties of structures with their potential applications in the fields of magnetism, catalysis, electrochemical properties, supercapacitors, energy-storage devices, etc. has led to an emerging field. The chapter covers recent developments in the field of heterometallic polyoxotungstate nanoclusters, with the aim of describing new structures, methodologies, characterisation techniques, and their applications.
