| 摘 要： | 采用柠檬酸络合法合成了钙钛矿型 Sr Fe O3-λ复合氧化物 ,以其为催化剂对不同水溶性染料溶液进行降解脱色试验 ,各种染料的脱色率均较高 ,表明 Sr Fe O3-λ具有很好的催化活性 ,这主要与 Sr Fe O3-λ中 Fe离子的变价和存在大量氧空位有关。

| Abstract: | Perovskite type oxide SrFeO 3 λ is prepared by citric acid complex method.It is used in catalytic destruction of water soluble dyes as a catalyst.The higher decolorization rates are obtained.It shows that pe rovskite type oxide SrFeO 3 λ has high catalytic activity,which mainly depends on the varible valence of ferric ion and oxygen vacancies in the compound. |

| Keywords: | SrFeO_(3-λ) Catalytic destruction Valence Oxygen vacancies |
