The synthesized CoFePBA@SBM catalyst exhibited superior physicochemical properties, including high specific surface area, robust structural stability, and abundant active sites, as characterized by SEM, TEM, XPS, and XRD analyses. The catalytic efficiency of CoFePBA@SBM in activating PMS was systematically evaluated under varying operational parameters, demonstrating remarkable IBP removal efficiency (up to 95.9 %) across a wide pH range. Mechanistic investigations revealed that both radical (SO₄^•−, HO^•, O₂^•−) and non-radical (¹O₂) pathways contributed significantly to the degradation process, supported by quenching experiments, EPR analysis, and DFT calculations. The proposed degradation pathways were elucidated through LC-MS, highlighting adequate mineralization into CO₂ and H₂O with minimal byproduct toxicity.

Simultaneously, the spread of both intracellular and extracellular ARGs was suppressed through the regulation of host microbial communities, specifically reflected in the reduced abundance of ARGs, decreased abundance of cell membrane permeability genes and the type IV secretion system.

More importantly, the disinfection performance of WO_3-x/MoS₂ was strongly dependent on the oxygen vacancy (OV) concentration in precursor WO_3-x.
