To improve the activation efficiency of PMS to efficiently degrade antibiotic sulfadiazine (SD), herein, a Co@MoS₂ catalyst was prepared by a one-step hydrothermal process. The unique petal-like structure of MoS₂ enables the transition metal Co to achieve high dispersion and avoid agglomeration. Mo(IV) and unsaturated S accelerate the electron transfer between Co${}^{2+}$ and Co${}^{3+}$ to improve the cycling efficiency and thus realize the efficient activation of PMS. The results of active substance quenching experiment and ESR analysis show that the main active substance for the efficient degradation of SD by Co@MoS₂ is the non-radical ¹O₂, while the other three radicals $\cdot {\mathrm{\text{O}}}_2^{-}$, ⋅OH and ${\mathrm{\text{SO}}}_4^{•-}$ contribute significantly to the efficient degradation of SD. And after 5 cycles, the degradation could still be as high as 90%. The strong consolidation of Co on the petal-shaped sheet of MoS₂ ensures the stability of Co@MoS₂ catalyst.

为了提高PMS的活化效率以有效降解抗生素磺胺嘧啶（SD），本文通过一步水热法制备了Co@MoS _{2催化剂。 MoS 2}独特的花瓣状结构使过渡金属Co能够实现高度分散并避免团聚。 Mo(IV)和不饱和S加速Co之间的电子转移${}^{2+}$和公司${}^{3+}$提高循环效率，从而实现PMS的高效激活。活性物质猝灭实验和ESR分析结果表明，Co@MoS ₂高效降解SD的主要活性物质是非自由基¹ O ₂，​​而其他三种自由基$\cdot {\mathrm{\text{氧}}}_2^{-}$, ⋅OH 和${\mathrm{\text{所以}}}_4^{•-}$对SD的有效降解有显着贡献。 5个循环后，降解率仍高达90%。 Co在MoS ₂花瓣状片材上的牢固固结保证了Co@MoS ₂催化剂的稳定性。
