| 摘 要： | 章介绍了具有合成H2O2和光催化性能的双功能新型复合电极，并用X－射线衍射，SEM等方法进行了表征，双功能复合电极是将TiO2/C光催化剂负载在具有合成H2O2性能的新型载体上形成的，在光反应器中，复合电极作阴，钌－钛不溶性电极作阳极，低压汞灯作光源，实现了光化学氧化与光催化氧化在同一电极／溶液界面上的联合作用，实验结果表明，复合电极对提高偶氮染料分子活性艳红（K－2BP）的氧化降解速度起到了重要作用，仅反应3min，脱色率可达49％，80min，偶氮染料分子可降解47％。

| Abstract: | A novel composite electrode which have functions of synthesizing H2O2 and photocatalysis was reported and characterized by X-rays and SEM. This double function composite electrode was prepared by loading photocatalyst TiO2/C on a novel carrier which can synthesize H2O2. In photo reactor, the composite electrode used as cathode, Ru-Ti electrode used as anode, lower pressure Hg lamp used as light source. Combining oxidation of photochemistry and photocatalysis exists at the same interface of electrode-solution. The experiment results showed that the composite electrode played important role in enhancing the oxidation rate of azo dye molecule, namely,in 3 min, the decolorizing rate could reach about 49%, and removing COD rate could reach about 47% only in 80 min. |
