| Abstract |
| Polyaniline-modified TiO2 nanotube arrays (PANI/TNTs) were fabricated by a constant voltage electropolymerization
method. The self-organized TiO2 nanotube arrays with an inner diameter of approximately 100 nm and a length of
4 m were prepared by a two-step anodization at 20 V for 3 h, and then the polyaniline was deposited on the surface
of the TiO2 nanotube arrays. The phase composition, morphology and property of PANI/TNTs were characterized by
X-ray diffraction, scanning electron microscopy, fourier transform infrared spectroscopy and UV-vis diffuse
reflectance spectroscopy. The prepared PANI/TNTs showed enhanced visible light absorption and corresponding
visible light photocatalytic activity. Furthermore, the PANI/TNTs also exhibited higher electrochemical behaviour
than that of TiO2 nanotube arrays.
