Triboelectric catalysis is a new technology that converts mechanical energy to chemical energy. This study presents a novel efficient triboelectric catalytic design based on iron (Fe) and polytetrafluoroethylene (PTFE). The tribocatalytic effect was evaluated by degrading methyl orange (MO), crystal violet (CV), and tetracycline (TC). The degradation efficiency can reach 95, 97, and 93% within 24 min, respectively, and the kinetic constant of CV was as high as 0.1460 min. The comparison with the stirring experiment showed that the friction catalytic effect between Fe and PTFE was significantly enhanced under ultrasonic irradiation. Furthermore, the triboelectric effect is used to provide simplicity and strong triboelectric catalytic activity of Fe/PTFE, and the influencing factors are analyzed. And the production of reactive oxygen species (ROS) of hydroxyl radicals and superoxide radicals increases during the catalytic process. The mechanism of triboelectric catalysis is discussed in terms of electron transfer and transition. This study utilizes the triboelectric effect of Fe/PTFE to provide simplicity and superior triboelectric catalytic activity under ultrasonic irradiation.
摩擦电催化是一种将机械能转化为化学能的新技术。本研究提出了一种基于铁（Fe）和聚四氟乙烯（PTFE）的新型高效摩擦电催化设计。通过降解甲基橙（MO）、结晶紫（CV）和四环素（TC）来评估摩擦催化效果。降解效率在24分钟内分别可达95%、97%和93%，CV的动力学常数高达0.1460 min⁻¹。与搅拌实验的比较表明，在超声辐照下Fe与PTFE之间的摩擦催化效果显著增强。此外，利用摩擦电效应实现了Fe/PTFE的简易性和较强的摩擦电催化活性，并分析了影响因素。在催化过程中，羟基自由基和超氧自由基等活性氧物质（ROS）的产生增加。从电子转移和跃迁的角度讨论了摩擦电催化的机理。本研究利用Fe/PTFE的摩擦电效应在超声辐照下实现了简易性和优异的摩擦电催化活性。
