Transition metal complexes as electrocatalysts—Development and applications in electro-oxidation reactions

In this review, the utilization of coordination compounds as electrocatalysts in a number of electro-oxidation reactions including oxidation of olefins, alcohols, water, glucose, nitric oxide and other small molecules is discussed. The coordination compounds function either as redox mediators and/or oxidative catalysts in the electrocatalytic reactions. Applications of the electrocatalysts in electro-synthesis, biosensing and biofuel cells are discussed with reference to the role played by the coordination compounds in these processes or technologies.
