摘要

通过简单的水热法，首次成功地一步合成了掺杂缺陷Fe的MIL-68(In)-NH2（Fe-MIL68），用于光催化降解双酚A（BPA）。利用现代表征技术证实了掺杂铁的Fe-MIL68中存在介孔结构和氧空位，可显著改善其吸附性能和电子-空穴分离能力，从而提高其光催化活性。结果表明，在可见光下，Fe-MIL68 在 100 分钟内对双酚 A 的光降解效率可达 92.3%，是 MIL-68(In)-NH2的 2.1 倍。

One-step construction of defective Fe-doped MIL-68(In)–NH2 for efficient photocatalytic degradation of bisphenol A

Defective Fe-doped MIL-68(In)–NH₂ (Fe-MIL68) was successfully synthesized for photocatalytic bisphenol A (BPA) degradation in one step via a simple hydrothermal method for the first time. The presence of mesoporous structure and oxygen vacancies in Fe-doped Fe-MIL68 was confirmed using modern characterization techniques, which can significantly improve its adsorption performance and electron-hole separation ability, thus enhancing its photocatalytic activity. The results confirmed the photodegradation efficiency of Fe-MIL68 for BPA under visible light could reach 92.3 % in 100 min, which was 2.1 times higher than that of MIL-68(In)–NH₂.
