摘　　要：本文介绍了掺Fe3+纳米TiO2催化剂的制备方法,讨论了在空气电极上负载掺Fe3+纳米TiO2光电催化氧化染料活性艳红的机理、特点以及影响催化反应的各因素。结果表明在最佳工艺条件下,活性艳红的降解率为92.8%This paper introduce the method of preparing catalyst by mixing with nanosized TiO_2 and doping Fe^(3+) ions.We also discuss the mechanism and characters of photo catalysis、electric catalysis and photoelectric catalysis oxidize sewages by air electrode which carries nanosized TiO__2 doped Fe^(3+) ions. And factors effecting the catalyst reaction also have been discussed. First, we use the method of sol-gel to prepare catalyst by doping Fe^(3+) ions in nanosized TiO_2, then degrade the waste water of dyestuffs (use red activation as reactant) by using EC (electric catalysis), PC(photo catalysis) and PEC(photoelectric catalysis) methods respectively.The result shows that all method can degrade the waste water of even nitrogen dyestuffs.The best condition of degradation was found by investigation of the different quantity of TiO_2 and Fe^(3+) ions.In the best condition, we discuss the effects of the react-condition to degradation rate and the catalytic activity, we found that the method is best when PH is 3 and the quantity is 0.1%. The rate of degradation is 66.8% in this best condition.
