This review systematically summarizes the basic strategies to enhance the catalytic performance of metal-organic frameworks (MOFs) in sulfate radical (SO4 center dot-)-based advanced oxidation processes (SR-AOPs), including modulating metal clusters and organic ligands, as well as introducing optimization, modification, and composite strategies. The preparation methods, characterizations, catalytic performances, and mechanisms of several typical MOFs are highlighted in this review. The prospects and challenges of MOFs applied to SR-AOPs are also discussed.
Organic pollutant contamination is a general issue. Sulfate radical (SO4 center dot-)-based advanced oxidation processes (SR-AOPs) is an efficient technology for degradation of organic pollutants in aquatic environment. Metal-organic frameworks (MOFs) have been widely applied to activation of persulfate (PDS) and peroxymonosulfate (PMS) due to their tunable metal clusters/organic ligands, large surface area, well-ordered porous structure, and multiple active sites. Herein this review systematically and comprehensively summarizes basic strategies to enhance catalytic performance of MOFs in SR-AOPs. Two main factors to modulate MOFs are metal clusters and organic ligands. Three strategies of optimization, modification, and composite are introduced. The preparation methods, characterizations, catalytic performances, and mechanisms of several typical MOFs are highlighted. In addition, the prospects and challenges of MOFs applied to SR-AOPs are declared.
