Nanomaterials, Год журнала: 2025, Номер 15(5), С. 386 - 386

Опубликована: Март 2, 2025

Contact-electro-catalysis (CEC) has emerged as a promising catalytic methodology, integrating principles from solid-liquid triboelectric nanogenerators (SL-TENGs) into catalysis. Unlike conventional approaches, CEC harnesses various forms of mechanical energy, including wind and water, along with other renewable sources, enabling reactions under natural conditions without reliance on specific energy inputs like light or electricity. This review presents the basic discusses its applications, degradation organic molecules, synthesis chemical substances, reduction metals. Furthermore, it explores methods to improve efficiency by optimizing conditions, structure catalyst materials, start-up mode. The concluding section offers insights future prospects potential applications CEC, highlighting role in advancing sustainable technologies.

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.
