采用电子束蒸发方法在透明导电玻璃FTO上沉积Ti金属薄膜, 室温条件下在C2H6O2+NH4F中通过恒压阳极氧化法制备出超长TiO2纳米管阵列/FTO电极, 并通过场发射扫描电子显微镜（FESEM）, 透射电子显微镜（TEM）, X光电子能谱（XPS）, X射线衍射（XRD）及光谱分析等方法对纳米管阵列/FTO电极进行了表征. 研究表明, 制备出的TiO2纳米管阵列内径43nm, 管长5.4μm, 经退火处理后得到长度为5μm锐钛矿相TiO2纳米管阵列/FTO透明电极, 在可见光波长段的透射率为45%, 在400nm波长处有一明显吸收峰.
Titanium film was deposited on fluorinedoped tin oxidecoated glass substrate (FTO) by electron beam evaporation (EBEAM), ultralong titania nanotube arrays/FTO electrode was fabricated by potentiostatic anodization of the titanium film in C2H6O2+NH4F electrolyte at room temperature. The structure and the composition of the titania nanotube arrays/FTO electrode were characterized by field emission scanning electron microscope (FESEM), transmission electron microscope (TEM), X-ray photoelectron spectroscope (XPS), X-ray diffraction (XRD) and transmission spectrometer. The results show that inner diameter and length of the asprepared titania nanotube are 43nm and 5.4μm respectively. The titania nanotube arrays/FTO transparent electrode after annealing in air is of anatase phase with length of 5μm. The transmittance of the titania nanotube arrays is 45% in visible wavelength range and an absorbance peak is observed at wavelength of 400nm.
