Abstract

Electro-Fenton has drawn tremendous attention due to in-situ H₂O₂ formation via two-electron oxygen reduction reaction (ORR) and electro-reduction of Fe²⁺/Fe³⁺. The cathodic two-electron ORR determines •OH generation rate and its total concentration. Therefore, this review concludes H₂O₂ accumulation mechanism in an overall process perspective including the strategy to enhance oxygen mass transfer, to improve two-electron reactivity/selectivity, to reduce/hinder invalid H₂O₂ decomposition. Moreover, the application of the electro-Fenton process was concluded. Finally, an outlook on future research challenges on electro-Fenton is proposed.
