Recent Progress of MIL MOF Materials in Degradation of Organic Pollutants by Fenton Reaction

Abstract

In recent years, environmental pollution has become more serious, especially the organic pollutants. Metal organic frameworks (MOFs) are promising materials used to degrade pollutants recently. Among them, Materials Institute Lavoisier frameworks (MILs) have been widely engaged due to their good stability and unique structural characteristics. This paper systematically analyses and summarizes the progress of MILs in degradation of organic pollutant by Fenton reaction in recent years. The MILs, especially four types of MILs, including MIL-100, MIL-101, MIL-88, and MIL-53, are first described and classified. Then, the common synthesis methods (hydrothermal synthesis, steam-assisted synthesis, and microwave-assisted synthesis) of MIL are summarized and compared. Modification and activation of MILs to obtain good degradation effect are also introduced and discussed. Finally, the applications of MILs in Fenton reaction are reviewed and their future development is prospected.

“…This overexpressed ROS production is utilized by cancer cells for various purposes, such as drug resistance, tumor pathogenesis, and metastasis (Ishikawa et al, 2008;Chun et al, 2021). The bi-MIL-88B MOFs, due to their trinuclear oxo cluster with terminal Treatment groups (μg/mL) Cell line 5-FU bi-MIL-88B 5-FU@bi-MIL-88B 5-FU@bi-MIL-88B-FC Frontiers in Pharmacology frontiersin.org coordinatively unsaturated sites (CUS), are capable of decomposing H 2 O into highly toxic • OH radicals (Xiao et al, 2023). These • OH radicals are highly potent and can oxidize any macromolecules that come in contact with them (Li H. et al, 2022).…”
