摘要：Peroxymonosulfate (PMS)-based three dimension-electrochemical advanced oxidation processes (3D-EAOPs) have received increasing attention, but the precise impact of electric field (EF) on particle electrodes (PEs) and integrated system remains poorly understood. This study presented the critical role of EF-induced polarized PEs in the effective activation of PMS and dissolved oxygen, and the subsequent enhancement of overall pollutant remediation. The Co, N-doped bio-polyporphyrin-derived activated carbon (Co-NC@PPAC) PEs were prepared by in-situ growth of zeolitic imidazolate frameworks-67 (ZIF-67) on vanillin-based polyporphyrin followed by pyrolysis. The synergistic effect between the electrochemical catalytic and Co-NC@PPAC catalytic processes in 3D-EF/Co-NC@PPAC/PMS system achieved an enhanced activity for nitenpyram (NTP) degradation, attaining 96.9 % removal rate within 60 min. Mechanistic studies confirmed that singlet oxygen (1O2) produced from the activation of PMS and dissolved oxygen in the cathodic chamber was the dominant reactive oxygen species (ROS) for pollutant degradation. Theoretical calculation results showed that the polarization of PEs with tunable Cophase could subtly regulate the adsorption and cleavage of PMS, as well as the activation of dissolved oxygen, which resulted in different NTP degradation mechanism. COMSOL Multiphysics simulation confirmed that the ROS involved in NTP degradation mainly originated from the activation of PMS and dissolved oxygen. This study highlighted a promising approach to construct highly cost-effective electrochemical treatment system and proposed a possible mechanism for 3D-EF/PEs/PMS electrochemical process.
