The electrochemical water treatment process using the insoluble electrode, the chemical reaction occurs through the electrode, which is the most important factor determining the water treatment ability and treatment efficiency of the electrode. The performance characteristics of the electrode vary greatly depending on various parameters of the manufacturing process, and the oxidant generation characteristics and the current efficiency are different depending on the material of the catalyst electrode layer of the electrode. The effects of the material and composition of the catalyst electrode layer on the chlorine oxidizer formation characteristics were evaluated in order to improve the utilization of the insoluble electrode as a water treatment electrode. The ruthenium dioxide ($RuO_2$) electrode, the iridium dioxide ($IrO_2$) electrode, the platinum (Pt) electrode, and the mixed metal oxide electrode (MMO) are used in the platinum-based insoluble electrode used in the water treatment. In this study, it was confirmed that the ruthenium-based catalyst electrode layer was the most effective, especially the electrode containing palladium was more excellent as a result of comparing the production characteristics of the chlorine-based oxidizing agent for the single material electrode and the composite material electrode.
