“…The coexistence of multiple reactive species can take full advantage of the oxidative capacity of PMS, producing major intermediates with significantly lower biotoxicity. 59–61 This work involves both radical and non-radical pathways and the results of the quenching experiments confirm that the non-free radical pathway is more dominant. It is more effective for TC removal and less toxic for the intermediates produced during degradation.…”

“…Subsequently, the recycling of Co@rGO-N,S was explored, as presented in Figure d. The Co@rGO-N,S/PMS system showed no obvious loss of the degradation efficiency over the first 5 cycles and maintained its performance, completely degrading TC within 60 min in the 8th cycle; it performed much better than Co@rGO/PMS . In conclusion, N and S doping on Co@rGO improved the performance of PMS treatment in TC degradation, and simultaneously enhanced the system adaptability, stability, and reusability by establishing a fully and stronger non-radical oxidation pathway.…”

“…Previous studies have demonstrated the higher resistance to ambient interference of non-radical pathways, and the cooperation of multiple oxidation pathways was believed to benefit TC degradation in the PMS system. , Given the structure and the former analysis of Co@rGO-S,N, it can be inferred that S doping would increase the stability against environmental interferences, while the effect of N doping on the TC degradation efficiency was unpredictable. Therefore, the influence of heteroatom doping on the performance of Co@rGO was studied, and the selectivity for various contaminants was also determined.…”
