TiO2-xNx nanotubes by selective doping of atomic nitrogen states and method for preparing the same

摘要

The invention TiO _{2 - x} N _x (0.01 x 0.2) nanotube, and relates to a manufacturing method thereof, and more particularly, using a plasma formed from a nitrogen gas TiO ₂ by treating the nanotubes TiO ₂ by the step of replacing the oxygen with nitrogen in the structure that partially doped with nitrogen in an atomic TiO _2-x N _x relates to a process for the production of the nanotubes. ; The invention TiO ₂ is the electronic structure being nitrogen doping the nanotube is controlled band gap ( band gap) is enhanced by the reduction in conductivity due to light absorption area is also being extended to the visible region from ultraviolet light, the electrochemical TiO having an improved application performance _{2 - x} N _x provides a nanotube.
