“…Fe ion leaching was observed to be 0.19 mg L –1 in the MIL-101(Fe)/PMS process, which is nontoxic to the environment . Fe-MIL-101 on nanofibers of polyacrylonitrile was effectively synthesized, and it was observed that the amount of Fe leaching was 0.13 mg L –1 , which is less as compared to various other Fe-based MOF studies …”

“…The cubes are linked together by additional metal ions and ligands to form a three-dimensional porous network. Most of the MILs have an octahedral nanocrystal shape within a range of 100–800 nm. , The specific composition, size of the metal ions, and organic ligands used in MILs can be tailored to achieve specific characteristics, like larger specific surface area, large pores, chemical stability, etc. Various research performed to evaluate the usage of MIL-MOFs as PMS/PS precursors in degradation experiments are listed in Table .…”

The degradation of organic pollutants present in domestic and industrial effluents is a matter of concern because of their high persistence and ecotoxicity. Recently, advanced oxidation processes (AOPs) are being emphasized for organic pollutant removal from effluents, as they have shown higher degradation efficiencies when compared to conventional activated sludge processes. Sulfate radical-based methods are some of the AOPs, mainly carried out using persulfate (PS) and peroxymonosulfate (PMS), which have gained attention due to the ease of sulfate radical generation and the effective degradation of organic molecules. PMS is gaining more popularity because of its high reactivity and ability to generate excess sulfate radicals. PMS has been the major focus; therefore, its mechanism has been explained, and limitations have been elaborated. The involvement of metal−organic frameworks for PMS/PS activation applied to organic pollutant removal and recent advances in the application of biochar and hydrogel-assisted metal−organic frameworks have been discussed.

“…Most PS-AOP systems have good adaptability to acidic conditions but poor adaptability to alkaline environments. 24,44,48,56,69,92,95 Zhou et al reported that the CuS@MIL-101(Fe)/PMS system showed the best performance for COU degradation at the initial solution pH of 3, and the reaction rate was gradually declined with the increase of pH. 83 The CuS@MIL-101(Fe) has a pH pzc (point of zero charge) of 4.5.…”

“…Abundant mixed-valence CUS with vacant p orbitals can further act as Lewis acid sites to provide floors for oxidant activation . The most reported CUS as active metal sites for PS activation included Fe(II) CUS in Fe MOFs, ,− Co(II) CUS in Co MOFs, ,,− and mixed-metal CUS such as Fe(II)/Co(II)-, ,,− Cu(II)/Co(II)-, Fe(II)/Cu(II)-, , and Mn/Fe-containing MOFs. , Generally, these metal CUS of M n + /M ( n +1)+ can undergo mutual transformation during the PS activation. The CUS commonly work as a single electron channel for the single metal MOFs, not directly involved in the reaction.…”

The persulfate activation-based advanced oxidation process (PS-AOP) is an important technology in wastewater purification. Using metal–organic frameworks (MOFs) as heterogeneous catalysts in the PS-AOP showed good application potential. Considering the intrinsic advantages and disadvantages of MOF materials, combining MOFs with other functional materials has also shown excellent PS activation performance and even achieves certain functional expansion. This Review introduces the classification of MOFs and MOF-based composites and the latest progress of their application in PS-AOP systems. The relevant activation/degradation mechanisms are summarized and discussed. Moreover, the importance of catalyst-related interfacial interaction for developing and optimizing advanced oxidation systems is emphasized. Then, the interference behavior of environmental parameters on the interfacial reaction is analyzed. Specifically, the initial solution pH and coexisting inorganic anions may hinder the interfacial reaction process via the consumption of reactive oxygen species, affecting the activation/degradation process. This Review aims to explore and summarize the interfacial mechanism of MOF-based catalysts in the activation of PS. Hopefully, it will inspire researchers to develop new AOP strategies with more application prospects.
