以钒钛合金为原料,应用阳极氧化法制备出高度致密、有序的V掺杂TiO2纳米管阵列。应用扫描电镜（SEM）和粉末X光衍射仪（XRD）表征分析纳米管阵列的形貌和结构,结果表明在浓度不同的HF电解液下制备出径向不同的纳米管阵列,电解液浓度（0.5%～1.5%（质量分数））,管径变化（39.7～72.7nm）。在室温、可见光照射条件下,以10mg/L的亚甲基蓝溶液为模拟污染物进行光催化降解试验,研究了其光催化性能。结果显示V掺杂TiO2纳米管阵列光催化性能优于纯TiO2纳米管,且在HF电解液浓度为1.0%（质量分数）时制备出来的TiO2纳米管光催化降解有机毒物性能最佳。

The titanium vanadium alloy as raw material,using anode oxidation method,the highly dense,ordered vanadium doped titania nanotube arrays were fabricated.The nanotube arrays characterization of morphology,composition and structure were determined by scanning electron microscope（SEM）,energy disperse spectroscopy（EDS） and powder X-ray diffraction（XRD）,the results showed that the different weight concentrations of HF electrolyte prepared by radial different nanotube arrays,with the weight concentration of the electrolyte HF changing from（0.5% to 1.5wt%）,the variation of nanotube arrays＇ diameters was from 39.7 to 72.7nm.At room temperature,under visible light irradiation,photocatalytic degradation of 10mg/L methyleneblue solution was carried out to test its photocatalytic properties.The results showed vanadium doped titania nanotube arrays photocatalytic properties of titania nanotube arrays is better than that of pure sample S1,and the samples were fabricated under HF electrolyte weight concentration 1.0wt% have more photocatalytic efficiency than other experimental conditions.The mechanism was briefly discussed.
