摘要
通过电化学阳极氧化法在(NH4)2SO4+NH4F溶液中恒压氧化纯钛箔,制备出TiO2纳米管阵列.研究了氧化电压、后处理清洗对纳米管形貌的影响;利用扫描电子显微镜(SEM)观察了TiO2纳米管阵列的微观形貌;采用X-射线衍射分析(XRD)表征了TiO2纳米管阵列的物相.
Anodic oxidation was adopted to prepare TiO2 nanotube arrays, which were prepared isobarically by the anodization of pure Ti in （NH4）2SO4 ＋ N H4 F electrolyte. The effect of applied voltages and fluorine concentration on the morphology of TiO2 nanotube was studied. The titania nanotube arrays were characterized with SEM and XRD.
