Abstract
Pt/N-codoped TiO2 nanotubes were prepared and characterized by various analytical methods, such as transmission electron microscope (TEM), diffuse reflection spectra (DRS), X-ray powder diffraction (XRD), X-ray photoelectron emission spectroscopy (XPS) and fluorescence spectra (FL). The photocatalytic efficiency was evaluated by the photodegradation of Rhodamine B (RB) in an aqueous solution under visible light irradiation. It has been confirmed that Pt/N-codoped TiO2 nanotubes could be excited by visible light and the recombination rate of electron-hole pairs declined significantly. The higher visible light activity is due to the codoping of nitrogen and platinum.
