主 题：Magnetically separable catalysts AOPs Sulfate radicals Mechanism Reusability
摘 要：In recent years,persulfate(PS)-based advanced oxidation processes(AOPs)have become a hot research topic for degrading environmental pollutants due to their excellent oxidation capacity,selectivity,and ***-AOPs can generate sulfate radicals(SO^(·-)_(4))with strong oxidation ability,but single PS produces limited or no ***,activation of PS by energy input or catalyst dosing is used to improve its oxidation ***,the addition of disposable catalyst not only causes a waste of resources,but also may lead to secondary ***,magnetically separable catalysts for activating PS have received widespread attention due to their *** there are few literature reviews on the activation of PS by carbon-or iron-based magnetic materials,the mechanism analysis of the activation of PS by magnetic materials to degrade pollut-ants is not deep enough,and the discussion of material types is not comprehensive and ***,the discussion of magnetic materials in terms of recycling properties is ***,this review firstly sum-marizes and analyzes the mechanism of magnetically separable catalysts activating PS to degrade ***,the research progress of zero-valent iron(ZVI,Fe^(0))-based,iron oxide-based,bimetallic oxide-based,and other magnetically separable catalyst is introduced,and the tailoring engineering approaches and reusability of magnetically separable catalysts are ***,some possible material optimization suggestions are proposed in this *** conclusion,this review is expected to provide useful insights for improving the per-formance and reusability of magnetically separable materials activated PS in the future.
