The Electro-Fenton process primarily involves two key steps:
Electrochemical Generation of H2O2: In this step, oxygen is reduced at the cathode in the presence of a suitable electrolyte, typically an acidic solution, to form H2O2. Fenton Reaction: The H2O2 produced is then catalytically decomposed by ferrous ions (Fe2+) to produce hydroxyl radicals (•OH), which are potent oxidizing agents capable of breaking down complex organic molecules.
