摘要：The Electro-Fenton (EF) technology has received significant research attention because of its efficacy in the degradation of persistent organic pollutants (POPs), which mainly relies on the in-situ generation of H2O2 via the 2-electron oxygen reduction reaction and the subsequent formation of .OH. However, the practical application of the EF technology still needs to deal with shortcomings such as the limited performance of the traditional het-erogeneous catalyst and the restricted generation of .OH that could be overcome by performing modification on the cathode. This work reviewed the reported cathode modification methods including thermal and (electro) chemical treatment and modification based on materials such as metals, graphene, carbon nanotubes, and polymers. Furthermore, the documented performances of the EF systems with differently modified cathodes in degrading specific POPs were presented. Finally, the advantages and limitations of these cathode modification methods were discussed, and some research perspectives were proposed to improve the practicability and feasibility of the EF technology.
