N/S-doped biochar-loaded Bi and FeS activated persulfate-driven ¹O₂ efficient degradation of ofloxacin.

ABSTRACT: Biochar-loaded Fe-based bimetals have been shown to be an effective catalyst for the activation of peroxodisulfates. However, reports on heteroatom-doped biochar-loaded Bi and FeS bimetals are scarce, and their properties and mechanisms remain unclear. In this study, NS₄-Bi₁FeS_0.75 catalysts were constructed using reductive hydrothermal and calcination methods. The results showed that the reductive hydrothermal process made Bi and FeS tightly bound, thereby promoting the stability of the catalyst. Under the optimal conditions, the NS₄-Bi₁FeS_0.75 system could completely degrade ofloxacin (OFX) within 20 min. Moreover, the NS₄-Bi₁FeS_0.75 system had excellent stability and regeneration capabilit
