Abstract EN
Highly ordered nitrogen-doped titanium dioxide (N-doped TiO2) nanotube arrays were prepared by anodic oxidation method and then annealed in a N2 atmosphere to obtain N-doped TiO2 nanotube arrays.
The samples were characterized with scanning electron microscope (SEM), X-ray powder diffraction (XRD), X-ray photoelectron spectrum (XPS), and UV-visible spectrophotometry (UV-vis) spectrum.
Degradation of the insecticide acephate under the visible light was used as a model to examine the visible-light photocatalytic activity of N-doped TiO2 nanotube arrays.
The results show that N type doping has no notable effects on the morphology and structure of TiO2 nanotube arrays.
After N type doping, the N replaces a small amount of O in TiO2, forming an N–Ti–O structure.
This shifts the optical absorption edge and enhances absorption of the visible light.
N-doped TiO2 nanotube arrays subjected to annealing at 500°C in N2 atmosphere show the strongest photocatalytic activity and reach a degradation rate of 84% within 2 h.
