Boosting Reactive Oxygen Species Generation via Contact‐Electro‐Catalysis with Fe^III‐Initiated Self‐cycled Fenton System

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 64(1)

Published: Aug. 22, 2024

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

There is growing focus on electrochemical oxidation of methane due to greater availability renewable electricity and the desire move cleaner production methane-based bulk chemicals. We analyze economic feasibility methanol, formaldehyde, formic acid, ethanol, acetic acetaldehyde, propanol at different scales (1, 10, 100, 1000 tonnes/day) determine key performance metrics (electricity price, current density, selectivity, conversion, stack cost) that enable production. The results show price cost are most important indicators, suggesting critical deployment hurdles need be addressed efficiency cost. With grid emission factors, all processes competitive compared thermal–catalytic processes.

FeIII-Driven Self-Cycled Fenton via Contact-Electro-Catalysis for Water Purification

Published: April 29, 2025

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.
