Production of high pure hydrogen from water electrolysis requires the development of highly effective and robust electrocatalysts for both oxygen (OER) and hydrogen evolution (HER) reactions. For several years, the development of new catalytic materials with various morphology, structure and composition has attracted attention of the worldwide researchers. Their main goals were to reach an improvement in activity, selectivity and stability of the electrocatalysts with a minimum of cost. However, many articles published the dependency of these reactions to noble metals (e.g. Pt, Ru Ir). In this chapter, past findings and latest development of metal oxides and Pt-based materials as anode and cathode catalysts, respectively, are summarized. Furthermore, the role of morphology and electronic structure of the nanocatalysts is also discussed to understand the mechanistic basis of their electrocatalytic performances.
