The coupling of hemin with persistent free radicals induces a nonradical mechanism for oxidation of pollutants

Abstract

Herein, we report that persistent free radicals (PFRs) based on MWCNTs significantly accelerate the pollutant removal rate. EPR measurement combined with the electrochemical test indicated that a nonradical mechanism was responsible for the enhancement, which is different from the previously reported radical pathway on PFRs.
