Abstract

Trititanate nanotubes were prepared by hydrothermal method and N was introduced into the nanotubes by ion-exchanging. They were characterized with X-ray photoelectron spectra (XPS), high-resolution transmission electronmicroscopy (HRTEM), X-ray diffraction (XRD) and UV-Vis diffusion reflection spectroscopy (UV-Vis DRS). The photocatalytic activities were investigated with Rhodamine B as the model pollutant. The results indicated that N-doping enhanced the photocatalytic efficiency of TiO₂ in visible light regions significantly.
