| Research Abstract |
The present work explores new processes for the crystallization of anodic TiO_2 nanotube layers and the nitrogen-doping into TiO_2 nanotube layers. TiO_2 nanotube layers prepared are also characterized. After the two-step anodization nocrystallization takes place within nanotube layers whereas anodization in organic electrolytes at elevated temperatures leads to the partial crystallization of anodic TiO_2 nanotubes. Nitrogen-doped TiO_2 nanotube layers formed by anodization of nitrogen containing Ti alloys exhibit visible light photocatalytic activities.
