The catalyst, in conjunction with periodate technology, exhibited TC degradation rates above 92 % in a broad pH range (3–11) and complex aqueous matrices. A comprehensive investigation was conducted to examine the impact of the catalyst quality, solution pH, contaminant concentration, and the presence of common anions on TC degradation.

The structural, morphological, and optical properties of the synthesized nanoparticles were systematically characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and UV–Visible spectroscopy. XRD analysis confirmed the successful incorporation of Mg&lt;sup&gt;2+&lt;/sup&gt; ions into the ZnO lattice, evidenced by lattice parameter shifts and a significant reduction in crystallite size from 30.91 nm (pure ZnO) to 18.10 nm (6 % Mg doping). SEM images showed uniform morphology with reduced particle agglomeration at optimal doping levels, while FTIR analysis identified characteristic Zn-O and Mg-O bonding vibrations, confirming structural integrity. UV–Vis spectroscopy revealed strong absorbance in the UV region, with the band gap energy decreasing from 3.68 eV (pure ZnO) to 3.16 eV (6 % Mg doping), indicating enhanced optical properties conducive to improved photocatalytic performance. The photocatalytic activity of Mg-doped ZnO nanoparticles was evaluated by degrading Basic Fuchsin (BF) dye under UV light irradiation. The Mg-doped ZnO nanoparticles exhibited significantly enhanced photocatalytic performance compared to undoped ZnO, achieving a maximum degradation efficiency of 99.38 % at 6 % Mg doping within 100 min. Optimal photocatalytic conditions were observed at pH 6, using 0.1 g of catalyst and an initial dye concentration of 10 ppm. These enhancements were attributed to improved electron-hole pair separation and increased generation of reactive oxygen species (ROS), facilitated by the strategic incorporation of Mg. To complement the experimental findings, Density Functional Theory (DFT) simulations were performed, integrating the Conductor-like Screening Model for Realistic Solvation (COSMO-RS), Reduced Density Gradient (RDG), and Quantum Theory of Atoms in Molecules (QTAIM). The DFT analysis revealed enhanced charge separation, optimized electron transfer dynamics, and stronger adsorption interactions at Mg-doped sites, which promoted efficient ROS generation.

This environmentally friendly approach aimed to integrate silver nanoparticles into the MoS<sub>2</sub> matrix. The synthesized nanocomposites was characterized using several techniques Fourier transform infrared spectroscopy (FT-IR) confirmed functionalization, UV visible spectroscopy (UV–Vis) revealed optical properties, and Field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) provide insights into its morphology.

The results demonstrated significant antibacterial activity, with decreased bacterial proliferation and colony forming abilities in concentration dependent manner. The enhanced performance was attributed to the synergistic effects of silver nanoparticles, which exhibit dual mechanisms by releasing silver ions and direct interaction with bacterial cell membranes. This study suggests that the Guar-gum functionalized 2D-MoS<sub>2</sub> (GG-Gel-MoS<sub>2</sub>-Ag-1.0) is a promising antibacterial material with potential applications in medical and environmental fields.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"176 ","pages":"Article 114296"},"PeriodicalIF":4.4,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143610964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
