Chapter 9: Catalysis by Oxometalates and Their Microheterogeneous Media

Applications of oxometalates in catalysis have been a long and ongoing endeavour. In this chapter, in addition to archiving the chemistry of oxometalates in catalysing oxidative, reductive and photoredox reactions along with acid and base catalysed reactions, we will highlight examples of reactions that can harvest energy. We will go further and introduce the micro-heterogeneous media or the state of soft-oxometalates in diverse catalysis. The overview concludes with a perspective on the future directions of catalysis research with oxometalates.
