英文摘要	In order to further enhance the activation performance of peroxymonosulfate (PMS), an efficient and recyclable ferromagnetic catalyst was successfully fabricated by co-precipitation and hydrothermal methods. We designed commercial hexagonal sheet boron nitride (C-BN) and boron nitrogen micro-nanotubes (BNMTs) to anchor CoFe2O4 nanoparticles (C-BN@CoFe2O4/BNMTs@CoFe2O4). Compared with smooth hexagonal C-BN, BNMTs were rich in pores and oxygen-containing groups. This could effectively immobilize CoFe2O4 to a certain extent, increase the loading of CoFe2O4 and enrich the active sites. Under optimal conditions, BNMTs@CoFe2O4/PMS system could rapidly and efficiently degrade 92.7% of oxytetracycline (OTC) within 5 min. In addition, the strong binding force between BNMTs and CoFe2O4 enabled favorable regeneration efficiency after 5 cycles (87.6%). BNMTs@CoFe2O4 activated PMS to generate hydroxyl radical (·OH), sulfate radical (SO4•-), superoxide radical (·O2–) and singlet oxygen (1O2) to further attack OTC, SO4•- and 1O2 were the main activities species. Meanwhile, there was also a non-radical mechanism for the activation of PMS by BNMTs@CoFe2O4, and OTC achieved a rapid and efficient degradation process through electron transfer. Our survey results were expected to provide new insights for the rational design and application of boron nitride-based materials and transition metal/PMS systems for environmental remediation. © 2022 Elsevier B.V.
