摘要：

Recoverable and stable nanocatalysts are essential for peroxymonosulfate-based advanced oxidation processes (AOPs) in wastewater purification treatment. In this paper, Fe3C nanorods @ nitrogen-doped carbon composites (N-Fe3C@C) with core-shell architecture were fabricated by the co-precipitation and calcination methods, and characterized and analyzed in terms of their crystal structure, microscopic morphology, and surface chemical elements. Furthermore, N-Fe3C@C-4 demonstrated an 85.36% degradation rate of tetracycline within 10 min under PMS based AOPs system, significantly surpassing the catalytic efficiency of Fe3O4 (42.03% in 10 min). The results from active radical trapping and EPR experiments corroborated the crucial role of1 O2 in the degradation of organic pollutants within the PMS system. The investigation on the degradation mechanism revealed that the presence of the carbon layer facilitated to adsorb TC, accelerate free radical generation and promote the redox cycle of Fe2+/Fe3+ in the nano-catalyst. This study offers novel ideas for multifunctional catalysts for advanced wastewater purification treatment. © 2024 Trans Tech Publications Ltd, All Rights Reserved.
