| 摘 要： | 研究了在不同浓度的NaCl电解质溶液中，悬浮TiO2-钛电极体系的光电催化降解效率。当降解时间达到60min时，单独光催化降解甲基橙的降解率为50．7％；在10V电压下进行光电催化反应，以0．5mol／LNaCl为电解质时，可使甲基橙降解率达到98．9％。光电催化法对甲基橙的降解率明显高于光催化法和电降解法，电降解和光催化降解之间存在着协同效应，且降解效率随着外加电压和NaCl溶液浓度的增大而提高．

| Abstract: | Photoelectrocatalytic degradation efficiencies in different concentration of NaCl solution with different applied potential are investigated. Photocatalytic degradation rate is 50.7% after 60 minutes of irradiation. When 10V voltage is applied, photoelectrocatalytic degradation rate is 98.9% in 0.5M NaCl solution. Obviously, photoelectrocatalytic degradation of methyl ficiency than that of photocatalytic process and electrodegre lation process. The between electrolysis and photocatalysis and the degradation rate increases with being increased. |
