Abstract:

Ag⁄N co–doped TiO₂ nanotube arrays (TNTs) were prepared by anodic oxidation, a certain amount of Ag deposited on the surface of TNTs by photodeposition and annealing post-treatment. The doped TNTs were characterized by field-emission scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and UV–vis diffusion reflection spectroscopy (UV–vis DRS). The photocatalytic activities of the prepared TiO₂ were evaluated by degrading rhodamine B (RhB) under visible light irradiation (≤ 420 nm). The photocatalytic degradation efficiency of the Ag/N-TNTs obtained for the degradation of RhB are 0.32 times, 0.6 times and 1.86 times higher than that of TNTs, N–TNTs, AgTNTs, respectively.
