Abstract Contact Electro‐Catalysis (CEC) using commercial dielectric materials in contact‐separation cycles with water can trigger interfacial electron transfer and induce the generation of reactive oxygen species (ROS). However, inherent hydrophobicity limits effective reaction sites, generated ROS inevitably undergo self‐combination to form hydrogen peroxide (H 2 O ). In typical CEC systems, H does not further decompose into ROS, leading suboptimal rates. Addressing activation is therefore crucial for advancing CEC. Here, we synthesized a catalyst by loading material polytetrafluoroethylene (PTFE) onto ZSM‐5 (PTFE/ZSM‐5, PZ short), achieving uniform dispersion first time. The introduction an Fe III ‐initiated self‐cycling Fenton system (SF‐CEC), synergistic effects ‐activated , enhanced generation. SF‐CEC system, protonated azo dyes enabled nearly 99 % degradation within 10 minutes, sixfold improvement compared system. This represents fastest rate methyl orange dye induced ultrasound date. Without extra oxidants, this stable dissolution precious metals weakly acidic solutions at room temperature, 80 gold hours, 2.5 times faster than similar systems. study also corrects unfavorable perception applications under conditions, providing new insights fields metal recovery.
