Zinc molybdate nanoparticles with molybdate are synthesized through green method with different salt precursors using Moringa oleifera leaf extract. Those nanoparticles had structural, vibrational, and morphological properties, which were determined by X-ray diffraction (XRD). The crystalline size of synthesized zinc molybdate was 24.9 nm. Fourier transform infrared (FTIR) spectroscopy and field emission scanning electron microscopy (FE-SEM) clearly showed the attachment of molybdate with ZnO. The synthesized nanomaterial was also characterized through UV-visible spectroscopy which had 4.40 eV band gap energy. Those nanoparticles were also characterized via thermogravimetric analysis (TGA-DTA) and photoluminance spectroscopy (PL). ZnMoO₄ had photocatalytic property via methylene blue dye. After 190 minutes, the dye changed to colourless from blue colour. The degradation efficiency was around 92.8%. It also showed their antibacterial effect via Escherichia coli and Staphylococcusaureus bacterial strains. In the presence of light and air, nanoparticles of ZnMoO₄ inhibit the growth of cells of E. coli and S. aureus bacterial strains because of ROS (reactive oxygen species) generation. Because of the formation of singlet oxygen (), hydrogen oxide radical (), and hydrogen peroxide (H₂O₂), ZnMoO₄ showed photodegradation reaction against aq. solution of methylene blue dye at 6 pH with constant time interval. With time, the activity of ZnMoO₄ also decreased because of the generation of a layer of hydrogen oxide (-OH) on nanomaterial surface, which could be washed with ethanol and distilled water. After drying, the catalytic Zinc molybdate nanoparticles could be reused again in the next catalytic reaction.

钼酸锌纳米粒子的仿生合成：一种有效抑制大肠杆菌、金黄色葡萄球菌和染料修复的材料

以辣木叶提取物为原料，用不同的盐前体通过绿色方法合成了含钼酸盐的钼酸锌纳米颗粒。这些纳米粒子具有结构、振动和形态特性，这些特性是通过 X 射线衍射 (XRD) 确定的。合成钼酸锌的晶体尺寸为24.9 nm。傅里叶变换红外 (FTIR) 光谱和场发射扫描电子显微镜 (FE-SEM) 清楚地显示了钼酸盐与 ZnO 的结合。合成的纳米材料还通过具有 4.40 eV 带隙能量的紫外-可见光谱进行了表征。这些纳米颗粒还通过热重分析 (TGA-DTA) 和光致发光光谱 (PL) 进行了表征。ZnMoO ₄通过亚甲基蓝染料具有光催化性能。190 分钟后，染料从蓝色变为无色。降解效率约为92.8%。它还通过大肠杆菌和金黄色葡萄球菌菌株显示出它们的抗菌作用。在光和空气存在的情况下，ZnMoO _{4纳米颗粒会抑制}大肠杆菌和金黄色葡萄球菌菌株的细胞生长，因为会产生 ROS（活性氧）。由于单线态氧 ( )、氢氧自由基 ( )和过氧化氢 (H ₂ O ₂ ) 的形成，ZnMoO ₄显示出对 aq 的光降解反应。pH 值为 6 且时间间隔恒定的亚甲蓝染料溶液。_{随着时间的推移，ZnMoO 4}的活性也随着纳米材料表面生成一层氧化氢（-OH）而降低，可用乙醇和蒸馏水清洗。干燥后的催化钼酸锌纳米颗粒可以在下一个催化反应中再次使用。
