While Self-cycled Fenton (SC-Fenton) systems represent an innovative advancement in water purification technologies, their practical implementation remains constrained by inefficient in-situ H2O2 generation. To address this limitation, we developed a mechano-driven contact-electro-catalysis (CEC) platform employing fluorinated ethylene propylene (FEP) as triboelectric catalyst. Under ultrasound irradiation, system achieves exceptional generation rate of 7.67 mmol·gcat–1·h–1, outperforming conventional piezo-catalysis systems. Mechanistic studies reveal that built interfacial electric field generated on FEP surface effectively reduces the free energy for indirect 2e– oxidation pathway. This unique characteristic promotes hydroxyl radical (*OH) and enhances its subsequent recombination into H2O2. The strategic integration FeIII catalytic initiator with CEC enables establishment SC-Fenton reaction (FeIII/FEP/CEC). Notably, contact-electrification electrons accumulated interface drive efficient FeIII/FeII redox cycling, achieving remarkable degradation sulfadiazine at 0.125 min–1. enhanced performance stems from FeIII-mediated amplification dissociative (•OH) study provides fundamental insights underlying mechanisms mediated FeIII-initiated reaction, offering new possibilities sustainable processes.
