Recent advance of Fe-based bimetallic persulfate activation catalysts for antibiotics removal: Performance, mechanism, contribution of the key ROSs and degradation pathways

• The features of various Fe-based bimetallic catalysts were comprehensively discussed. • The mechanisms of Fe-based bimetallic catalysts activating PMS/PDS were reviewed. • The workflows of reactive oxygen species (ROSs) identification were clarified in detail. • The calculation models of ROSs contribution rates were thoroughly organized. • The degradation pathways and toxicity assessment of antibiotics were presented. Antibiotic residues have been widely discovered in different types of water bodies, posing a critical risk to the water ecosystem and human health. Persulfate activation based advanced oxidation process (AOP), as an actual hot research topic for the removal of antibiotic contaminants from water…
