Tuning reactive chlorine species to singlet oxygen via peroxymonosulfate synergy: Ultra-efficient electrooxidation with minimal chlorinated byproducts.

Chlorination electrooxidation (EO/Cl) systems face challenges in balancing efficient pollutant degradation with hazardous chlorinated byproduct formation and unclear formation mechanisms of active species.

By adapting a refined quenching protocol, we identified contributions of key species (Cl/Cl, HOCl, Cl, and O), and unraveled the selective conversion mechanism of RCS to O in the EO/Cl⁻/PMS system.
