Abstract Herein, we demonstrate, the synthesis and photocatalytic properties of a metal organic framework derived calcium iron bimetallic oxide for degradation of organic dyes from water. Characterisation of the material revealed the formation of a mesoporous and crystalline Ca4Fe9O17 phase that had never been explored as a photocatalyst. The material exhibited an optical band-gap of ∼1.9 eV, a value ideally suited for visible light-driven catalysis. When tested as a photocatalyst for degradation of methylene blue, an organic cationic dye and a common contaminant of water, it showed impressive (>50%) dye degradation within two hours of illumination under low power lights.

金属有机骨架衍生的 Ca4Fe9O17 作为降解有机染料的光催化剂

摘要在此，我们展示了金属有机骨架衍生的钙铁双金属氧化物的合成和光催化性能，用于从水中降解有机染料。该材料的表征表明形成了从未被用作光催化剂的介孔结晶 Ca4Fe9O17 相。该材料表现出约 1.9 eV 的光学带隙，该值非常适合可见光驱动的催化。当测试用作降解亚甲蓝、有机阳离子染料和常见的水污染物的光催化剂时，它在低功率灯下照明两小时内显示出令人印象深刻的 (>50%) 染料降解。
