ABSTRACT
This chapter focuses on the fundamentals of electrocatalytic oxidation (EO) and to demonstrate an overview regarding the electrocatalysts employed in the technique for decontamination of wastewater, so as to offer to the readers an easy grasp and integral view of the field. Electrochemistry has a significant role in the EO technique, and the efficiency of the electrolytic cell depends on a number of parameters. A conceptual configuration of an electrocatalytic reactor for the decontamination of wastewater through electrooxidation includes a current supply, a cathode, an anode, and the electrolyte. As the electrocatalytic reaction takes place on the electrode surfaces, the most important challenge in the cell configuration is to maintain high mass transfer rates. The efficiency and selectivity of the electrocatalytic oxidation method are strictly directed by the nature of the electrode material. Of course, the EO technique has advantages as well as disadvantages, and both of them are elaborated.
