Enhanced Photocatalytic Performance of Nitrogen-Doped TiO<sub>2</sub> Nanotube Arrays Using a Simple Annealing Process

Nitrogen-doped TiO<sub>2</sub> nanotube arrays (N-TNAs) were successfully fabricated by a simple thermal annealing process in ambient N<sub>2</sub> gas at 450 °C for 3 h. TNAs with modified morphologies were prepared by a two-step anodization using an aqueous NH<sub>4</sub>F/ethylene glycol solution...
