本文用柠檬酸法合成钙钛矿型 Sr Fe O3-λ,并用水溶性染料在 Sr Fe O3-λ悬浮体系中进行光催化降解实验。实验发现了在 Sr Fe O3-λ化合物中 ,由于 Fe3+、Fe4 +、Fe5+离子的共存使 Sr Fe O3-λ具有优异的光催化染料降解活性。
In this paper, perovskite-type SrFeO3-λ was synthesized by citric acid method, and photocatalytic degradation experiments were carried out using water-soluble dyes in SrFeO3-λ suspension system. It was found that the SrFeO3-λ compound has excellent photocatalytic dye degradation activity due to the coexistence of Fe3 +, Fe4 + and Fe5 + ions in the SrFeO3-λ compound.
