Electrolyzed oxidizing water (EO water) is a new disinfectant, which has been proved to possess the high bactericidal efficiency against a wide variety of microorganisms ranging from bacteria to viruses. EO water is generated by electrolysis of an extremely dilute NaCl solution. Therefore, it is necessary to enhance the selectivity of chlorine evolution reaction (CER), which the oxygen evolution side reaction (OER) needs to be minimized. In the present study, the TiO2 doped IrO2-Ta2O5 (IrO2-Ta2O5-TiO2) electrode was prepared by the thermal deco...
