Adsorptive and photo-Fenton properties of bimetallic MIL-100(Fe,Sn) and MIL-100(Fe,Ir) MOFs toward removal of tetracycline from aqueous solutions
Abstract:
Bimetallic derivatives of MIL-100(Fe) are promising metal–organic frameworks (MOFs) that have caught
increasing research and application attention in the last few years due to their superior potential com-
pared to MIL-100(Fe) for treatment of wastewater. In this work, novel bimetallic MIL-100(Fe,Sn) and
MIL-100(Fe,Ir) were synthesized using a facile synthesis method. The synthesized MOFs showed different
activities toward removal of tetracycline (TC), a broad-spectrum antibiotic, from an aqueous solution
under dark conditions, followed by photo-Fenton degradation. In this context, the best-performing Sn-
doped MIL-100(Fe) MOFs, that is MIL-100(Fe,Sn-7.1), showed marginally increased adsorption and
photo-Fenton activity compared to MIL-100(Fe), resulting in a TC removal efficiency of 76%. In contrast,
the best-performing Ir-doped MIL-100(Fe), that is MIL-100(Fe,Ir-62.3), showed enhanced adsorption
property by 34% compared to MIL-100(Fe), resulting in the best TC removal efficiency of 91% among
the studied MOFs. The detailed analysis and characterization of the synthesized MOFs revealed that
the average pore diameter of MIL-100(Fe,Ir-62.3) was approximately four times larger than that of MIL-
