- W4285405576 abstract "Spinel sulfides are a good candidate as heterogeneous catalysts for wastewater treatment through peroxymonosulfate (PMS) activation. In this paper, magnetic Fe3O4/NiCo2S4 composite was successfully synthesized by hydrothermal method. Catalyst screening displayed that the composite catalyst with a Fe3O4:NiCo2S4 molar ratio of 1:3 (i.e.,0.33-Fe3O4/NiCo2S4) is the most optimal. The results showed that 0.33-Fe3O4/NiCo2S4 composite catalyst had superior catalytic activity, achieving 99.8%,65.1% and 40.7% of RhB, COD and TOC removals within 30 min with 180 m g/L PMS and 75 mg/L catalyst. We proposed a potential catalytic mechanism of PMS activation by Fe3O4/NiCo2S4 in two aspects. On the one hand, sulfur species such as S2− and S22− enhance the Co3+/Co2+, Ni3+/Ni2+ and Fe3+/Fe2+ cycles on Fe3O4/NiCo2S4 surface. On the other hand, there is the synergistic effect of Co3+/Co2+, Ni3+/Ni2+ and Fe3+/Fe2+ cycles in activating PMS. Overall, owing to its excellent catalytic activity, reusability, and easy recovery, Fe3O4/NiCo2S4 is a potentially useful catalyst for remediation of contaminated water." @default.
