A notable feature of the EF process is the continuous in situ production of hydrogen peroxide (H2O2) via two-electron oxygen reduction reaction (1). This enables a continuous flow of radical dotOH generated from Fenton’s reaction (2), which occurs in the presence of added Fe2+ [4], [5]. Furthermore, in EF systems, this ion can be efficiently regenerated via cathodic reduction (reaction (3)), thus enhancing the process sustainability [6]. The effective H2O2 generation and Fe2+ regeneration become pivotal factors to attain high degradation efficiencies in EF [7].1 p.application/pdfengcc-by-nc-nd (c) Zhang, Yue, et al., 2024http://creativecommons.org/licenses/by-nc-nd/4.0/FerroElectronsOxidació electroquímicaIronElectronesElectrolytic oxidationinfo:eu-repo/semantics/article7515532024-11-13info:eu-repo/semantics/openAccess
