TiO2 Nano-tube about 30 μm Prepared by Anodic Oxidation
摘 要
为制备更长的TiO2纳米管，在0，20，40 ℃的0.5%（质量分数，下同）NaF＋甘油溶液中，20 V直流电压条件下，对Ti片进行7 h阳极氧化，并采用SEM对纳米管进行了表征。结果表明：得到的TiO2纳米管长度分别为1.034 μm、2.601 μm和5.152 μm；电流密度测试结果表明：在20 ℃，40 ℃的0.5% NaF+甘油溶液中，平衡时阳极氧化电流密度分别为1.27 mA/cm2和1.50 mA/cm2左右；40 ℃条件下反应36 h，TiO2纳米管长度达到30 μm左右。

Abstract
In order to prepare longer TiO2 nano-tube, Ti sheet was anodically oxidized at direct voltage of 20 V in solution of 0.5(mass fraction)% NaF＋glycerin for 7 h, at the temperature of 0 ℃, 20 ℃ and 40 ℃ respectively. The results of SEM show that the length of the TiO2 nano-tube was 1.034 μm, 2.601 μm and 5.152 μm for 0 ℃, 20 ℃ and 40 ℃ respectively. The results of current density show that balance anodic current density in the solution of 0.5 NaF+glycerin at temperature of 20 ℃ and 40 ℃ was 1.27 mA/cm2 and 1.50 mA/cm2 respectively. At the temperature of 40 ℃, in solution of 0.5% NaF+glycerin, TiO2 nano-tube could grow to about 30 μm for 36 h of anodic oxidation.
