In the present work, multiple applications of natural clay loaded Samarium molybdate for photodegradation, sensing and antibacterial activity were analyzed. The clay-based materials have attracted great attention as they show good application prospects for environmental remediation. We developed natural clay loaded Sm₂MoO₆ (CSm₂MoO₆) nanocomposite, hydrothermally and characterized by XRD, SEM, HR-TEM, FT-IR and optical studies. XRD pattern of CSm₂MoO₆ exhibits peaks at 19.60, 27.80, 35.60 and 62.40 corresponding to clay and Sm₂MoO₆ peaks clearly indicates the formation of natural clay conjugated with Sm₂MoO₆. SEM image of the natural clay doped CSm₂MoO₆ nanoparticle shows a homogeneous distribution of spherical Sm₂MoO₆on nanoflakes of clay material. HR-TEM images reveal that the average particle size is 50 nm. Loading of natural clay material increased the visible absorption of Sm₂MoO₆ by reducing the band gap from 3.82 to 2.39 eV. Decomposition of 20 ppm of Metronidazole (MNZ) was 95% with 60 mg of CSm₂MoO₆ in 100 min of visible light illumination. Hydroxyl radicals played the main role for photodegradation of MNZ. Electrochemical analysis revealed that the oxidation peak current of 4-aminophenol has increased with a high potential at pH 6.0 and CSm₂MoO₆/SPCE electrode has an advantage of low detection limit of 0.005 $\mathrm{\mu }$M and a long linear range of 2949.72 $\mathrm{\mu }$M with a sensitivity of 5.29301 $\mathrm{\mu }$M. The synthesized nanocomposite has a significant bactericidal activity against Bacillus subtilis, Staphylococcus aureus, Proteus mirabilis, Bacteroides fragilis, E. coli and Candida albicans. These results make this green catalyst potential for multiple applications.

在目前的工作中，分析了天然粘土负载的钼酸mar在光降解，传感和抗菌活性方面的多种应用。粘土基材料因其在环境修复方面显示出良好的应用前景而备受关注。我们开发了水热天然负载粘土的Sm ₂ MoO ₆（CSm ₂ MoO ₆）纳米复合材料，并通过XRD，SEM，HR-TEM，FT-IR和光学研究进行了表征。CSm ₂ MoO _6的XRD图谱显示出在19.60、27.80、35.60和62.40处的峰，分别对应于粘土和Sm ₂ MoO ₆峰，清楚地表明了与Sm ₂共轭的天然粘土的形成。MoO ₆。天然粘土掺杂的CSm ₂ MoO ₆纳米颗粒的SEM图像显示球形Sm ₂ MoO ₆在粘土材料的纳米薄片上的均匀分布。HR-TEM图像显示平均粒径为50 nm。通过将带隙从3.82 eV减小到2.39 eV ，天然粘土材料的负载增加了Sm ₂ MoO ₆的可见吸收。用60 mg CSm ₂ MoO ₆分解20 ppm甲硝唑（MNZ）的95％在100分钟的可见光照射下。羟基自由基在MNZ的光降解中起主要作用。电化学分析表明4-氨基苯酚的氧化峰电流在pH 6.0时以高电势增加，CSm ₂ MoO ₆ / SPCE电极的检测限低至0.005。$\mathrm{\mu }$M和2949.72的长线性范围 $\mathrm{\mu }$M的灵敏度为5.29301 $\mathrm{\mu }$M.合成的纳米复合材料对枯草芽孢杆菌，金黄色葡萄球菌，变形杆菌，脆弱拟杆菌，大肠杆菌和白色念珠菌具有显着的杀菌活性。这些结果使这种绿色催化剂具有用于多种应用的潜力。
