The problem of water pollution has become an urgent global issue. As one approach for addressing this problem, in this work, rod-like ZnO nanostructures were synthesized by a simple electrodeposition method, which can purify wastewater by photocatalytic reaction. ZnO was deposited on indium tin oxide (ITO) conductive glass by electrodeposition, and then the surface of the sample was modified by 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane to make the surface super-hydrophobic. ZnO nanorods with a “photocatalytic and self-cleaning” synergistic effect were obtained. The morphology and structure of the samples were analyzed by field emission scanning electron microscopy (FESEM) and x-ray diffraction (XRD). FESEM images show that different deposition times, water bath temperatures, electrolysis times, and electrodeposition voltages have different effects on the surface morphology of the materials. XRD patterns show that the crystal structure of nano-ZnO is a hexagonal wurtzite crystalline structure. The optical properties of the samples were characterized by UV–Vis spectrophotometry. The hydrophobicity of the materials was characterized using a droplet shape analyzer. Photocatalysis results show that the modification can improve the photocatalytic efficiency of the materials. The results show that the material has excellent optical properties, and because of its super-hydrophobicity, there are no residual small particles on the surface after the photocatalytic reaction. Therefore, this material not only has high photocatalytic performance, but can also be recycled for treatment of water pollution.

水污染问题已成为一个紧迫的全球性问题。作为解决这个问题的一种方法,在这项工作中,通过简单的电沉积方法合成了棒状 ZnO 纳米结构,它可以通过光催化反应净化废水。通过电沉积将ZnO沉积在氧化铟锡(ITO)导电玻璃上,然后用1H、1H、2H、2H-全氟癸基三乙氧基硅烷对样品表面进行改性,使表面具有超疏水性。获得了具有“光催化和自清洁”协同效应的 ZnO 纳米棒。通过场发射扫描电子显微镜(FESEM)和X射线衍射(XRD)分析样品的形貌和结构。FESEM 图像显示不同的沉积时间、水浴温度、电解次数、和电沉积电压对材料的表面形貌有不同的影响。XRD图谱表明纳米ZnO的晶体结构为六方纤锌矿晶体结构。样品的光学性质通过紫外-可见分光光度法表征。使用液滴形状分析仪表征材料的疏水性。光催化结果表明,改性可以提高材料的光催化效率。结果表明,该材料具有优异的光学性能,并且由于其超疏水性,光催化反应后表面无残留小颗粒。因此,这种材料不仅具有很高的光催化性能,而且还可以回收用于处理水污染。XRD图谱表明纳米ZnO的晶体结构为六方纤锌矿晶体结构。样品的光学性质通过紫外-可见分光光度法表征。使用液滴形状分析仪表征材料的疏水性。光催化结果表明,改性可以提高材料的光催化效率。结果表明,该材料具有优异的光学性能,并且由于其超疏水性,光催化反应后表面无残留小颗粒。因此,这种材料不仅具有很高的光催化性能,而且还可以回收用于处理水污染。XRD图谱表明纳米ZnO的晶体结构为六方纤锌矿晶体结构。样品的光学性质通过紫外-可见分光光度法表征。使用液滴形状分析仪表征材料的疏水性。光催化结果表明,改性可以提高材料的光催化效率。结果表明,该材料具有优异的光学性能,并且由于其超疏水性,光催化反应后表面无残留小颗粒。因此,这种材料不仅具有很高的光催化性能,而且还可以回收用于处理水污染。样品的光学性质通过紫外-可见分光光度法表征。使用液滴形状分析仪表征材料的疏水性。光催化结果表明,改性可以提高材料的光催化效率。结果表明,该材料具有优异的光学性能,并且由于其超疏水性,光催化反应后表面无残留小颗粒。因此,这种材料不仅具有很高的光催化性能,而且还可以回收用于处理水污染。样品的光学性质通过紫外-可见分光光度法表征。使用液滴形状分析仪表征材料的疏水性。光催化结果表明,改性可以提高材料的光催化效率。结果表明,该材料具有优异的光学性能,并且由于其超疏水性,光催化反应后表面无残留小颗粒。因此,这种材料不仅具有很高的光催化性能,而且还可以回收用于处理水污染。结果表明,该材料具有优异的光学性能,并且由于其超疏水性,光催化反应后表面无残留小颗粒。因此,这种材料不仅具有很高的光催化性能,而且还可以回收用于处理水污染。结果表明,该材料具有优异的光学性能,并且由于其超疏水性,光催化反应后表面无残留小颗粒。因此,这种材料不仅具有很高的光催化性能,而且还可以回收用于处理水污染。
