A new method for deposition nitrogen‐doped TiO2 nanofibers with mixed phases of anatase and rutile

A new method for deposition nitrogen-doped TiO2 nanofibers films was proposed. By using atmospheric pressure plasma jet generated by dual-frequency power sources, the morphologies of these TiO2 films were investigated by scanning electron microscopy. The structures of these films were characterized by X-ray diffraction and Raman Shift Spectroscopy. The elemental composition of these films [Colour figure can be viewed at wileyonlinelibrary.com] were characterized by means of X-ray photoelectron spectroscopy. The optical absorption of these films were studied by UV-vis absorbance spectra. These results indicated that the nitrogen-doped nanofibers TiO2 films have mixed phases of anatase and rutile. They also display narrow band gap. The I-V characteristics curves exhibited good conductivity ability. Optical emission spectroscopy (OES) was measured to analyze the active group.
