The electro-Fenton (EF) process is an indirect electrochemical process based on Fenton's reaction chemistrywhile Fenton's reagent is partially or completely generated from electrode reactions.
Generally, H2O2 is generated at the cathode with O2 or air feeding,
and Fe2+ is generated when an iron elementary substance exists in acidic solution.
Nevertheless, introducing iron particles and air simultaneously into the electrochemical process has never been reported apart from our group
