摘要:Metal-free catalysis is considered promising for the green degradation of aqueous organic pollutants. Herein, a novel non-metallic heteroatom-doped boron nitride (h-BN) catalyst with carbon and sulfur doping, named SC-BN, was successfully prepared. Under optimal conditions, the SC-BN/peroxymonosulfate (PMS) system can achieve an impressive 99.4 % levofloxacin removal within 90 min (k(obs) = 0.0531 min(-1)). In-depth physicochemical characterizations have identified B-N-C and C-S-C as co-active functional groups. The electrochemical characterization and density functional theory (DFT) calculations further verified the enhanced electron transfer pathway (ETP) at S sites, which was activated by an emerging electric field. h-BN as a highly electroactive material also plays a positive role in regulation. Besides, the electrical energy per order (EE/O = 6.65 kWh/m(3)) and toxicity evaluation results exhibited the practical potential for eco-friendly detoxification and degradation of various refractory contaminants. In summary, this study puts forth a novel metal-free PMS activation process with an efficient multi-path mechanism and provides a theoretical foundation for future research.
