Furthermore, the Ag nanoparticles employed in sewage treatment are challenging to recycle, resulting in environmental pollution and resource wastage. Herein, the Ag-core Fe₃O₄-shell structured particles (Ag@Fe₃O₄) are synthesized by leveraging the reduction potential difference between Ag⁺/Ag⁰ and Fe³⁺/Fe²⁺ through a one-step polyol reduction process. The Fe₃O₄ shell in the Ag@Fe₃O₄ composite not only effectively inhibits the agglomeration of Ag, but also enhances the penetration capability of the composite into biofilms, thereby enabling Ag@Fe₃O₄ to possess remarkable antibacterial efficacy against Escherichia coli (<em>E. coli</em>). The Ag@Fe₃O₄ demonstrates nearly 100 % inhibition of <em>E. coli</em> at a concentration of 0.24 mg mL⁻¹ (with an Ag content of 0.042 mg mL⁻¹) while still maintaining antibacterial effectiveness of 74.6 % even after undergoing reutilization for 10 cycles. Meanwhile, due to the excellent electron conductivity of Ag and the effective adsorption capability of Fe₃O₄ shell towards organic dyes, Ag@Fe₃O₄ facilitates rapid electron transfer to organic dyes and further lead to their reduction and degradation in the presence of NaBH₄. The Ag@Fe₃O₄ can catalytically degrade various organic dyes (including Rhodamine B, Rhodamine 6G, and Methylene blue) within only 15 min, while achieving an impressive degradation efficiency exceeding 90.9 % after 6 cycles of reutilization. The cost-effectiveness (approximately $0.17 per gram), facile magnetic recovery, along with the superior antibacterial and dye-degradation performance showcase the significant potential of Ag@Fe₃O₄ for medical applications and sewage treatment.</div></div>","PeriodicalId":249,"journal":{"name":"Arabian Journal of Chemistry","volume":"18 1","pages":"Article 106058"},"PeriodicalIF":5.3,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142653326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In solution, the oxidation of BOH (with orange fluorescence) by the two cations occurred at the ethylene group (C<img>C) locating between the dipyrrole and phenol groups and resulted in conjugation-truncated products exhibiting characteristic green fluorescence emission. In heterogeneous small unilamellar vesicles (SUV), water soluble ABTS^•+ was evidenced to oxidize BOH embedded in the lipid bilayers of SUV, while Fe³⁺ did not. The lack of reaction between Fe³⁺ and BOH was attributed to the complexation between Fe³⁺ and the phenolic hydroxyl group of BOH on the surface of the SUV. The reaction kinetics results indicated that, in homogeneous solution, the oxidation rate of Fe³⁺ was three orders of magnitude slower than that of ABTS^•+ for BOH. The location and orientation of BOH within the SUV were discussed based on the reaction phenomena. BOH could be as a good antioxidant fluorescent prober for ABTS^•+ detection with a detection limit of 1.5 * 10⁻⁷ M and a linear rang of 0–4.93 μM.

MXenes have demonstrated immense potential as future materials for adsorption purposes. They have proven to be highly effective in removing emerging pollutants (heavy metals and organic pollutants) through the adsorption phenomenon. The effectiveness of MXenes in removing lead (Pb²⁺), chromium (Cr⁶⁺), copper (Cu²⁺), uranium (U⁶⁺), and mercury (Hg²⁺) has been confirmed, with a sorption capacity ranging from 100 to 250 mg g⁻¹. Furthermore, MXenes have effectively removed several radionuclides, including uranium, europium, strontium, barium, and thorium. MXenes have proven to be highly efficient in treating water through adsorption in emerging organic pollutants, even for various organic dyes such as methylene blue, acid blue, congo red, methyl orange, and rhodamine B (RhB). Additionally, MXenes exhibit high treatment performance in adsorbing several pharmaceuticals like cloxacillin (CLX), ampicillin (AMP), amoxicillin (AMX), ciprofloxacin (CPX), amitriptyline (AMT), verapamil (VRP), carbamazepine (CBM), 17 α-ethinyl estradiol, ibuprofen (IBP), and diclofenac (DCF).
