The Pivotal Role of Selenium Vacancies in Defective FeSe₂@MoO₃ for Efficient Peroxymonosulfate Activation: Experimental and DFT Calculation

ACS ES&T Engineering, Год журнала: 2023, Номер 4(1), С. 153 - 165

Опубликована: Июль 19, 2023

The presence of selenium vacancies (VSe) in metal selenides enables the activation peroxymonosulfate (PMS) for efficient water purification. However, mechanisms interactions VSe with PMS and organic pollutant removal are unclear. Hence, we precisely prepared a series FeSe2@MoO3 composites effective various pollutants. roles explored via density functional theory (DFT) calculations: (i) regulating electron distribution Fe Mo orbitals enhancing adsorption (ii) promoting conversion transition metallic redox pairs (Fe3+/Fe2+ Mo6+/Mo5+/Mo4+). as-prepared FeSe2@MoO3-8 exhibits excellent catalytic performance which nearly 100% efficiencies pollutants achieved within 2–10 min. quenching experiments, electronic spin resonance (ESR), probe tests demonstrated that multiple reactive species like SO4•–, O2•–, •OH, 1O2 contributed to 2,4-D. Finally, was attached polyvinylidene difluoride (PVDF) membrane continuous 2,4-D, efficiency total carbon 2,4-D were > 90% >70% 12 h operation.

Abstract The clinical application of oncology therapy is hampered by high glutathione concentrations, hypoxia, and inefficient activation cell death mechanisms in cancer cells. In this study, Fe Mo bimetallic sulfide nanomaterial (FeS 2 @MoS ) based on metal‐organic framework structure rationally prepared with peroxidase (POD)‐, catalase (CAT)‐, superoxide dismutase (SOD)‐like activities depletion ability, which can confer versatility for treating tumors mending wounds. the lesion area, FeS SOD‐like activity facilitate transformation anions (O − to hydrogen peroxide (H O ), then resulting H serves as a substrate Fenton reaction FMS produce highly toxic hydroxyl radicals ( ∙ OH). Simultaneously, has an ability deplete (GSH) catalyze decomposition nicotinamide adenine dinucleotide phosphate (NADPH) curb regeneration GSH from source. Thus it realize effective tumor elimination through synergistic apoptosis‐ferroptosis strategy. Based alteration system, free radical production, alleviation hypoxia microenvironment, NPS not only significantly inhibit vivo vitro, but also multidrug‐resistant bacteria hasten wound healing. It may open door development cascade nanoplatforms treatment overcoming infection.
