摘要

室温下在NH4F、乙二醇的混合溶液中采用阳极氧化法在纯Ti片表面组装一层结构高度有序且表面光滑的TiO2纳米管阵列．对TiO2纳米管阵列进行扫描电子显微镜(SEM)、X射线衍射(XRD)检测; 且检测了TiO2纳米管(锐钛矿型)在锂离子电池和光催化降解甲基橙等应用性能．结果表明, 制备得到了高密度排列的TiO2纳米管阵列; TiO2纳米管在锂离子的脱嵌过程中表现出较好的可逆性质. 溶液中加入H2O2可以提高TiO2纳米管光降解催化活性．

关键词： TiO2纳米管; 阳极氧化; 乙二醇

Abstract

Anodization of Ti using ethylene glycol containing 0.5wt％ NH4F as electrolyte resulted in ordered arrays of TiO2 nanotube with a smooth surface. Electrochemical anodization was carried out at room temperature. The microstructures and morphologies of the TiO2 nanotube were nvestigated by scanning electron microscope (SEM), X-ray diffraction (XRD). A series of studies were carried out to investigate the properties of TiO2 nanotubes (anatase) for lithium anode materials and for the materials of photocatalyzing degradation of aqueous methyl orange. The results show that high density, well ordered and uniform TiO2 nanotube arrays are fabricated. TiO2 nanotube shows a comparatively reversible reaction when it is used for lithium ion battery by CV measurement. Adding H2O2 into the solution can improve the photocatalysis of TiO2 nanotube.

Key words： TiO2 nanotubes; anodization; ethylene glycol
