| 摘 要： | 采用柠檬酸法合成钙钛矿型复合氧化物LaFeO3和SrFeO3,并以其为光催化剂对不同水溶性染料进行光催化降解实验.结果表明:SrFeO3的光催化活性明显高于LaFeO3,这与A位离子(La3+,Sr2+)的电子构型的不同有关.

| Abstract: | Pervoskite-type LaFeO 3 amd SrFeO 3 were prepared by citrate method,Using afluorescent Hg lamp as irradiator,the degradation experiments of various water-soluble dyes were carried out in the suspension systems of LaFeO 3 and SrFeO 3.The results show that the pervoskite-type LaFeO 3 and SrFeO 3 have photocatalytic activities,but the catalytic activity of SrFeO 3 is higher than that of LaFeO 3 The difference of photocatalytic activities is related to the electronic structure of the ion A(La 3+ ,Sr 2+ ) |
