Blue TiO2 nanotube array (blue TNA) has gained interest as a highly effective and low-cost material in electrochemical chlorine generation. Hydroxyl radicals mediated chlorine generation is the major pathway (indirect pathway) on the blue TNA which showed lower efficiency than direct pathway on dimensionally stable anodes. In this study, RuO2 coated blue TNA (blue TNA-RuO2) was fabricated, which exhibited a higher current efficiency (96%) than that of the blue TNA and RuO2. The excellent performance of the blue TNA-RuO2 is attributed to the simultaneous reaction of direct pathway on the RuO2 and indirect pathway on the blue NTA together.
