| Abstract: | Nanosized TiO2 has excellent photocatalytic activity to degrade most of pollutants.The most important focus has been on the improvement of photocatalytic activity and the efficiency of utilizing solar energy.The researches has proved that nonmetal-doping can activate its visible-light activity.Self-organized F-doped TiO2 nanotube arrays were fabricated by a one-step electrochemical anodization process on a Ti sheet.The prepared samples were annealed in air and detected by SEM,XRD and XPS.SEM imagesThe resul... |
