| 摘 要： | 以直接热氧化制备的TiO2为催化剂，研究了水中苯胺的光催化和光电催化降解行为。结果表明：外加阳极偏压可提高TiO2薄膜电极的光催化活性，但同时副反应速率增大更快，苯胺降解的光电流效率反而下降。

| Abstract: | The photocatalytic and photoelectrocatalytic degradation of aniline in water over thermally formed TiO 2/Ti photoanodes was investigated. The results showed that the photoactivity of TiO 2/Ti electrode could be improved largely under the external anodic bias potential, but the side reaction rate increased faster.As a result the photocurrent efficiency for aniline degradation decreased. |
