Abstract 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.

RuO 2 涂覆的蓝色TiO 2 纳米管阵列（蓝色TNA-RuO 2 ）作为电化学氯生成的有效阳极材料

摘要 蓝色 TiO2 纳米管阵列（蓝色 TNA）作为一种高效、低成本的电化学氯生成材料已引起人们的兴趣。羟基自由基介导的氯生成是蓝色 TNA 上的主要途径（间接途径），其效率低于尺寸稳定阳极上的直接途径。在本研究中，制备了 RuO2 涂层的蓝色 TNA（蓝色 TNA-RuO2），其电流效率（96%）高于蓝色 TNA 和 RuO2。蓝色TNA-RuO2的优异性能归因于RuO2上的直接途径和蓝色NTA上的间接途径同时反应。
