Polyoxometalates As Versatile Components for Hybrid Electrode and Electrolyte Materials

Polyoxometalates are inorganic clusters with a unique combination of physical-chemical properties, including a rich redox chemistry, electron and proton-transfer. Their zero-dimensional nature and small size set them apart from conventional electrode materials. Yet, some of their characteristic properties have made them useful components in electrode materials (i.e. electroactivity), whereas others represent opportunities for their application as electrolytes (i.e. solid acids, proton conduction). In this conference we will present examples of both types of applications for a variety of devices, from fuel cells to supercapacitors and discuss further potential uses of these clusters.
