Facilitating Efficient Electro-Fenton Degradation Using a Free-Standing Membrane Electrode with Atomic-Level Fe Dispersion Fabricated by Microwave-Assisted Electrospinning

) are the primary reactive oxygen species (ROS), with ·OH exhibiting significantly higher reactivity. The active sites and degradation pathways of the RhB molecule are further elucidated via density functional theory (DFT) and liquid chromatography-mass spectrometry (LC-MS) analyses. Notably, toxicity assessment indicates low environmental risk from most of the intermediates, indicating negligible potential for secondary environmental contamination. This study provides a novel strategy for designing high-performance, stable electro-Fenton cathodes showing broad application potential in organic wastewater remediation.
