以阳极氧化法制备了高度有序的 TiO2纳米管阵列，采用扫描电镜观察了不同制备条件下得到的 TiO 2纳米管阵列的微观形貌，分别考察了电解时间、电压、电解液组成对 TiO2纳米管阵列形貌的影响；此外，以酸性红3R 染料作为标志物，测定了制得的 TiO2纳米管阵列片的光催化性能．结果表明，以0．5％ NH4 F（质量分数）和乙二醇与水按体积比5∶1混合得到的溶液作为电解液，在15 V 电压下电解2 h ，得到的 TiO2纳米管阵列的纳米管管径适中（60 nm）、大小均一、排列整齐．所制备的 TiO2纳米管阵列对染料的降解率显著优于纳米 TiO 2水溶胶的，且其光催化性能与形貌、电解时间及煅烧温度等密切相关．

Highly ordered titanium dioxide nanotube arrays were prepared by anodic oxidation method .The morphology of TiO2 nanotube arrays obtained under different anodic oxidation conditions was observed with a scanning electron microscope ,and the influences of electrolysis time ,voltage ,and component of electrolyte on the morphology of as‐prepared TiO2 nanotube arrays were investigated .Moreover ,the photocatalytic performance of as‐prepared TiO2 nano‐tube arrays was evaluated with acid‐red 3R as the target compound to be degraded .It was found that ,when 0 .5% N H4 F (mass fraction) and glycol were mixed with water at a volume ratio of 5 ∶ 1 generating the electrolyte ,highly uniform ordered nanotube arrays with a moder‐ate tube diameter of 60 nm were obtained after 2 h electrolysis under a potential of 15 V .Re‐sultant TiO2 nanotube arrays exhibit much better photocatalytic performance than traditional TiO2 hydrosol .Moreover ,the photocatalytic performance of as‐prepared TiO2 nanotube arrays is closely related to the microstructure ,oxidation time ,and calcination temperature .
