    ABSTRACT:
    Electrocatalysis plays a pivotal role in electrochemical energy conversion devices such as fuel and electrolysis cells by decreasing the overpotential of electrode reactions. Understanding mechanisms of the electrode reactions and the nature of active sites and intermediates is an important clue in designing efficient and durable electrode materials for practical applications. Various approaches can be utilized in order to obtain information regarding the mechanisms of electrocatalytic reactions and the nature of the active sites; among them are electrochemical methods, operando spectroscopies, ab initio calculations and kinetic modeling. In this presentation, we will illustrate these approaches by considering reactions of outstanding practical importance [1-6] such as the oxygen reduction (ORR) and the oxygen evolution reaction (OER), the hydrogen evolution (HER) and the hydrogen oxidation reaction (HOR).
