Electrochemical synthesis of hydrogen peroxide (H₂O₂) via two-electron pathway of oxygen reduction reaction is a promising alternative to the current anthraquinone process. The H₂O₂ production from O₂ is a competing reaction with four-electron O₂ reduction to H₂O, and the selectivity is related to the adsorption energy of the OOH intermediate on electrocatalysts surface. Generally, the properties for binding of OOH intermediate on catalysts can be controlled by changing its electronic structure. Herein, the electronic structure of porous carbon materials was tuned by doping different types and contents of fluorine species. The yield of H₂O₂ generation depended on the F content and the best catalytic activity toward H₂O₂ electrosynthesis was obtained with F content of 3.41 at.%. The resultant F-doped porous carbon (FPC) catalysts exhibited good H₂O₂ selectivity of 97.5–83.0% and the H₂O₂ production rate could reach 112.6–792.6 mmol h⁻¹ g⁻¹ over the potential range of 0.2 V to −0.3 vs. RHE (pH 1). The density functional theory (DFT) calculations and experiments revealed that the incorporation of CF_{2, 3} into carbon plane promotes the activation of O₂ molecule and facilitates desorption of OOH intermediate, which was crucial to H₂O₂ synthesis.
