Efficient persistent organic pollutant removal in water using MIL-metal–organic framework driven Fenton-like reactions: A critical review

Abstract

• Recent developments on MIL-MOFs as Fenton-like catalysts were discussed. • Catalyst modifications for POP breakdown were elaborated. • The critical parameters for improving POP removal were highlighted. • Challenges and future directions for MIL-MOFs were presented. In recent years, metal–organic frameworks (MOFs) have stood out in their application in water pollutant degradation via Fenton-like-aided processes. The advent of Materials from Institut Lavoisier (MIL) MOFs has attracted more research to eliminate these target pollutants better. This review is focused on the current developments that enabled higher Fenton-like activity of MIL-MOFs towards the degradation of persistent organic pollutants (POPs) residing in water. For the first time, MIL-MOFs were evaluated in terms of POPs and Fenton-like reactions. The first section considers the structural modification of MIL-MOF catalysts examining their metal sites, additional units, and catalyst preparation. Moreover, the core factors based on the type of Fenton-like system and reaction parameters were assessed. A discussion was made on the potential practical applications and the current situation of Fenton-like reactions. To conclude, challenges and a comprehensive outlook were offered for researchers in wastewater treatment and crystalline material application to exploit these catalysts.
