Electrochemical oxygen reduction via the two-electron pathway (2e-ORR) is an emerging method for producing H2O2. It cleaner, safer, and more convenient compared to anthraquinone process. Graphite felt one of cathode candidates large-scale cells due its excellent mechanical properties. However, commercial graphite often fails achieve desired hydrogen-peroxide yield because low catalytic selectivity 2e-ORR pathway. Fluorine-doped carbon materials are expected enhance selectivity. This electronic structure atoms adjacent fluorine may facilitate production hydrogen peroxide while hindering further reduction. In this study, fluorine-doped graphene oxide (FGO) was prepared by hydrothermal method. Subsequently, modified with FGO fabricated used as H2O2 production. The results indicated that in alkaline media, achieved a 93% generation rate 8.91 mg cm⁻2 h⁻¹. comparison, had 75% 2.10 Moreover, also exhibited electrocatalytic performance neutral media. research provides fundamental study promote application environmentally friendly industries.
