abstract = {Bifunctional catalysts for H2O2 production via oxygen reduction reaction (ORR) and OH• generation via Fenton reaction are fundamental for the development and optimization of Electro-Fenton technology. In this context, Fe- doped carbon xerogels have been synthesized by sol-gel polymerization under hydrothermal conditions, which allowed the efficient encapsulation of iron nanoparticles (Fe3C-type crystalline species) within the carbon matrix. This strategy enabled control over the selectivity of the materials towards a three-electron pathway, favoring the direct production of hydroxyl radicals (OH•). Moreover, a good balance between graphitization degree and micro-mesoporous structure resulted in high electrochemical performance in ORR, reaching a kinetic current density as high as 11.56 mA/cm2 at −0.45 V and 32.66 mA/cm2 at −0.80 V. This remarkable performance was reflected in Electro-Fenton experiments, achieving 94% degradation of tetracycline after 8 h, demonstrating the bifunctional effectiveness of the synthesized catalysts.},
