Although there have been many studies on the mechanism of oxygen reduction, and many convincing theories have been proposed, there are still many details on the main reaction pathways for oxygen reduction which are not clear enough. So from the middle product ratio of the reaction and the influencing factors, we know that they are methods of continuous two-electron reactions. The main difference between the two-electron and the four-electron reaction pathway is the intermediate product. Due to the complexity of the oxygen reduction reaction, the path and mechanism of the reaction are mainly studied by experimental and theoretical calculations. The adsorption of oxygen on a metal catalyst can be regarded as adsorption on metal ions, similar to the case where metal and oxygen are bonded in a transition metal complex. It not only has the associative adsorption and dissociative adsorption adsorbed in molecular form but also the oxygen atoms can enter the interior of the metal lattice to form surface oxides. The adsorption of oxygen molecules on the surface of the catalyst is complicated. Therefore, the adsorption of O 2 on transition metals will be discussed in detail below. This chapter describes the mechanism and kinetics of oxygen reduction.
