Abstract：
The ordered mesoporous ZnO was successfully synthesized using the template method in this article, and Bi ions were etched into ZnO to form two-dimensional nanoflower structures of Bi12ZnO20 with NA3SSA as a guiding agent. The crystal structure, morphology, and optical properties of the photocatalyst were characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM), energy-dispersive spectrometer(EDS), and ultraviolet-visible diffuse reflectance spectrum (UV-vis DRS). Under illumination conditions, the obtained materials exhibited excellent bactericidal ability against both gram-positive and gram-negative bacteria, as well as effective inhibition against fungi. Among them, the bactericidal effect of Pseudomonas aeruginosa was found to be the most rapid, achieving a sterilization rate of 100% within 30 min of light irradiation. Even after three cycles of antibacterial activity testing, the Bi12ZnO20 material still demonstrated good photocatalytic performance. The nanoflower-shaped materials provide an enhanced fluid adsorption capacity and more active centers for photocatalytic reactions while also improving light absorption capacity, photogenerated electron-hole separation efficiency, and electron transport efficiency. The cytotoxicity assessment of Bi12ZnO20 revealed no significant toxic effects. Therefore, this study presents a nanoflower-shaped material with highly efficient photocatalytic antibacterial properties for applications in production and daily life; it holds significant importance in eliminating harmful bacteria and plays a crucial role in environmental protection.
OBJECTIVE: The flower-shaped photocatalytic material Bi12ZnO20, consisting of nanoparticles, was successfully synthesized in this study. Rigorous antibacterial experiments were conducted on various fungi using the material, yielding excellent results. Furthermore, the application of this material for antibacterial treatment of livestock and poultry manure sewage in real-life scenarios demonstrated remarkable efficacy.

摘要：
本文利用模板法成功合成了有序介孔ZnO,以NA3SSA为导向剂，将Bi离子刻蚀到ZnO中，形成Bi12ZnO20的二维纳米下层结构。晶体结构，形态学,用X射线衍射仪(XRD)对光催化剂的光学性能进行了表征,扫描电子显微镜（SEM），能量色散光谱仪（EDS），和紫外-可见漫反射光谱(UV-visDRS)。在光照条件下，所得材料对革兰氏阳性菌和革兰氏阴性菌均表现出优异的杀菌能力，以及有效抑制真菌。其中,铜绿假单胞菌的杀菌效果最迅速,在光照射30分钟内达到100%的灭菌率。即使经过三个周期的抗菌活性测试，Bi12ZnO20材料仍表现出良好的光催化性能。纳米软形材料提供了增强的流体吸附能力和更多的活性中心，用于光催化反应，同时还提高了光吸收能力，光生电子-空穴分离效率，和电子传输效率。Bi12ZnO20的细胞毒性评估显示没有显著的毒性作用。因此,本研究提出了一种具有高效光催化抗菌性能的纳米草状材料，应用于生产和日常生活中。它在消除有害细菌方面具有重要意义，在环境保护中起着至关重要的作用。
