Based on the advantages of electro-Fenton (EF) and our works on the flexible design of triboelectric nanogenerator (TENG) and biomass carbon materials, a self-powered EF system is demonstrated. It is driven by a robust and flexible multilayered TENG (RFM-TENG) using carbon materials derived from magnolia flowers as the cathode for oxygen reduction. The synthetic mesoporous carbon materials have a large surface area (1226 m² g⁻¹), favoring dissolved oxygen mass transfer and promoting the oxygen reduction process. With the sponge as the buffer layer and pre-charge injection, the short-circuit current, transferred charge and open-circuit voltage of RFM-TENG are 960 μA, 2.8 μC and 1050 V, respectively, and the maximum power density reaches 5.5 W m⁻² at a load resistance of 1 MΩ. Driven by this RFM-TENG, the persistent organic pollutant, basic orange 2, can be degraded to CO₂ by hydroxyl radical (•OH) generated during EF process. Such mechanism is proposed based on the cyclic voltammogram, gas chromatograph-mass spectrometer, UV−vis spectra and the H₂O₂ measurement. With compelling features of the efficient EF method, versatile TENG and biomass-derived carbon materials, this work pioneers the alliance of TENG, carbon-based electrodes and EF to self-power the organic pollutants degradation for sustainable environmental protection.

基于电子芬顿（EF）的优势以及我们对摩擦电纳米发电机（TENG）和生物质碳材料的灵活设计工作，展示了一种自供电的EF系统。它是由坚固而灵活的多层TENG（RFM-TENG）驱动的，它使用源自木兰花的碳材料作为氧还原的阴极。合成的中孔碳材料具有大的表面积（1226m ²  g ^-1），有利于溶解氧的质量传递并促进了氧的还原过程。以海绵作为缓冲层并进行预充电注入，RFM-TENG的短路电流，转移的电荷和开路电压分别为960μA，2.8μC和1050 V，最大功率密度达到5.5 W m ^-2在1MΩ的负载电阻下。在此RFM-TENG的驱动下，持久性有机污染物碱性橙2可以被EF过程中产生的羟基自由基（•OH）降解为CO ₂。基于循环伏安法，气相色谱-质谱仪，UV-vis光谱和H ₂ O ₂测量，提出了这种机理。凭借高效的EF方法，通用的TENG和源自生物质的碳材料的引人注目的功能，这项工作开创了TENG，碳基电极和EF的联盟，以自给自足地降解有机污染物，以实现可持续的环境保护。
