Electro-Fenton　(EF)　process,　featuring　in-situ　hydrogen　peroxide　(H2O2)　production,　has　received　increasing　attention　for　its　efficacy　in　degrading　organic　pollutants.　However,　challenges　such　as　low　oxygen　utilization　efficiency　and　high　energy　consumption　persist.　In　this　study,　a　novel　Carbon　Black-loaded　Carbon　Felt　(CB-CF)　electrode　using　the　electrophoretic　deposition　(EPD)　technique　was　prepared　to　boost　the　efficiency　of　H2O2　production.　Various　aeration　patterns　and　aeration　gas　were　systematically　introduced　to　assess　the　oxygen　utilization　pathway　and　improve　oxygen　utilization　efficiency.　The　CB-CF　cathode,　forming　an　efficient　triphase　interface,　coupled　with　the　side-oxygen　mode,　demonstrates　rapid　H2O2　production　(48.82　mg/h)　at　a　remarkably　low　energy　consumption　(14.46kWh·kg−1)　with　the　current　density　of　15　mA/cm2.　The　fabricated　CB-CF　exhibited　exceptional　performance,　achieving　over　90%　degradation　efficiency　of　Fulvic　Acid　(FA)　within　60　minutes　in　the　EF　system.　Stability　experiments　underscored　the　impact　of　current　density　and　hydrophobicity　on　the　electrode　but　revealed　that　PTFE　recoating　effectively　preserves　stability.　Furthermore,　the　straightforward　and　efficient　electrode　preparation　process,　combined　with　the　favorable　electrochemical　properties　of　CB-CF,　positions　it　as　a　promising　candidate　for　large-scale　applications　in　H2O2　electro-synthesis　and　environmental　remediation.　©　2024　Elsevier　Ltd
