This study utilizes ascorbic acid under hydrothermal conditions to composite ferric oxide (Fe3O4) and molybdenum disulfide (MoS2), preparing Fe@C-MoS2 with enhanced electron transfer for catalyzing the degradation of atrazine (ATZ) by peroxymonosulfate (PMS). Under the conditions of an ATZ concentration of 5mg/L, a catalyst dosage of 0.2g/L, and a PMS concentration of 1mmol/L, the removal rate of ATZ reached 84.6% after 35 minutes of reaction. Electrochemical experiments and XPS characterization demonstrated that the excellent catalytic performance of Fe@C-MoS2 is attributed to the carbon source-induced generation of mixed-phase MoS2, which effectively improves the conductivity of the catalyst and promotes rapid electron transfer. Additionally, through bio-toxicity tests using locally grown cauliflower as the study subject, the feasibility of using the solution degraded by the Fe@C-MoS2/PMS system as agricultural irrigation water was evaluated. The results indicate that the post-degradation solution showed negligible effects on both the survival rate of cauliflower seedlings and their growth parameters when compared with conventional water sources.
