Over hundread years, so many oxidation technologies have been developed in environmental engineering fields. Mostly, chemical and biological oxidation processes have been enough to treat organic and/or inorganic pollutants to meet the legal emission targets. However, recent wastewater including non-degradable organic compounds demands the development of advanced oxidation technology since non-degradable organic compounds are hardly decomposed by chemical and/or biological treatment technology. Particularly, discharge of toxic or highly concentrated industrial wastewater has been significantly increased due to rapid industrial development to be a serious water pollution. To overcome this problem, various water treatment technologies such as chemical oxidation, precipitation, adsorption, capacitive deionization, electrochemical oxidation and so on have been recently developed and introduced to industry. Among them, electrochemical oxidation of the compounds at anode is environmentally friendly, easily operated and maintained compared to conventional treatment processes. Nonetheless, cost reduction and enhancement of performance/durability of anodic electrodes are highly necessary for commercialization. In this study, TiO2/IrO2/RuO2 electrodes that IrO2 and RuO2 coated on anodized Ti substrate were prepared and investigated in terms of various electrochemical properties.
