Recent Achievements in the Analysis of the Electrochemical Properties of Polyoxometalates

Abstract

Polyoxometalates (POMs) have been studied for ca. 200 years since the first report on the synthesis of (NH 4 ) 3 PMo 12 O 40 in 1826. Even now, novel POMs are still being prepared, characterized and applied to various fields. Multi-step, multi-electron transfers reversibly occur for many redox active POMs, which is interesting to many electrochemists. Recently, the electrocatalytic behaviour of POMs has been focussed on due to the potential as a solution for energy problems. However, unclear aspects remain in terms of the fundamental electrochemical properties of POMs. This article reviews recent achievements on the electrochemistry of POMs in the solution phase.
