Description
Summary:Herein, a novel defective Fe-doped MIL-68(In)–NH2 was prepared for the first time and used for the efficient and environmentally friendly photocatalytic degradation of bisphenol A under visible light irradiation. [Display omitted] •A defective Fe-doped MIL-68(In)–NH2 was first prepared.•The Fe-MIL68 showed excellent activity for BPA degradation under visible light.•The Fe-doped, oxygen vacancy, and mesoporous structure contributed to the photocatalytic activity. 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.
