An innovative electro-fenton degradation system self-powered by triboelectric nanogenerator using biomass-derived carbon materials as cathode catalyst

Based on the advantages of EF process and our works on the flexible design of TENGs and carbon materials, we synthesize the carbon materials from magnolia flowers as the cathode for oxygen reduction and design a robust and flexible multilayer triboelectric nanogenerator (RFM-TENG) with the sponge as the buffer layer for the first time to realize the self-powered degradation of basic orange 2 (BO2) via electro-Fenton system. This work pioneers the combination of the TENG with biomass-based carbon materials to self-power electro-Fenton degradation of organic pollutants for environmental protection.218
