Oxygen evolution reaction (OER) is the anodic reaction in the overall water
splitting process. The four electron-proton reaction is thermodynamically nonspontaneous
and kinetically slow. Hence, the need for an electrocatalyst is urgently
required to achieve faster kinetics for OER and to enhance the rate of overall watersplitting
reaction. The chapter discusses the fundamentals; which include mechanisms
of OER, the characteristic features as well as kinetic performance parameters of OER
electrocatalyst and advances in nano-electrocatalysis; which includes recent
developments in TMO based electrocatalyst, strategies for improving the performance
of an electrocatalyst; catalyst other than TMOs. The present discussion offers profound
insight and interest on catalysts in oxygen evolution reactions.

Keywords: Electrocatalyst, Nano-catalyst, Overpotential, Oxygen evolution reaction, Transition metal oxides, Water splitting process.
