TiO2-xNx Nanotubes and Method for Preparing the Same

摘要

TiO_2-xN_x (0.01≦x≦0.2) nanotubes and a method for preparing the same are disclosed. More particularly, TiO_2-xN_x (0.01≦x≦0.2) nanotubes doped with nitrogen atoms by treating TiO₂ nanotubes through nitrogen plasma to partially substitute oxygen portion of TiO₂ nanotube with nitrogen, and a method for preparing the same are disclosed. The TiO_2-xN_x (0.01≦x≦0.2) nanotube of the present invention is prepared by doping nitrogen on a TiO₂ nanotube to control an electronic structure and reduce a band gap of the TiO₂ nanotube, so that the prepared TiO_2-xN_x (0.01≦x≦0.2) nanotube exhibits improved conductivity and extended light absorption range from a UV ray area up to a visible light area, thus having more enhanced applicable performance in optical and/or electrochemical aspects.
