The utilization of titanium dioxide (TiO 2 ) photocatalysis for water and air purification is a frequently used method due to TiO 2 having properties making it chemically inert, highly cost-effective, abundant, non-toxic, and environmentally-friendly. In an effort to increase the efficiency of the degradation process, an in-depth understanding of the effects of the structure and number of thin film coatings is needed. Transparent, anatase-form titanium dioxide thin films were prepared via the sol-gel method and deposited onto microscopic glass slides using a novel spraying technique , with coatings ranging from 1 to 10. Characterization of the TiO 2 thin film coated slides was performed using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The contribution shows that the coating technique is efficient in covering important areas of the surface and that it is suitable for a multiple coating layers thin film. The SEM imagines show that the surface of the slides increase coverage as the number of layers increases. This is potentially suitable for a mechanized spraying approach to upscaling the production of thin films for advanced oxidation applications.

通过薄膜光催化降解水溶液中的对乙酰氨基酚第一部分：二氧化钛薄膜的制备、表征和分析

利用二氧化钛 (TiO 2 ) 光催化净化水和空气是一种常用的方法，因为 TiO 2 具有使其化学惰性、成本效益高、丰富、无毒和环保的特性。为了提高降解过程的效率，需要深入了解薄膜涂层的结构和数量的影响。通过溶胶-凝胶法制备透明的锐钛矿型二氧化钛薄膜，并使用新型喷涂技术沉积在显微载玻片上，涂层范围为 1 至 10。使用 X 对涂有 TiO 2 薄膜的载玻片进行表征射线衍射（XRD）和扫描电子显微镜（SEM）技术。该贡献表明，涂层技术在覆盖表面的重要区域方面是有效的，并且适用于多层涂层薄膜。SEM 图像显示载玻片表面随着层数的增加而增加覆盖率。这可能适用于机械化喷涂方法，以扩大用于高级氧化应用的薄膜的生产。
