A self-organized nano-structured, photocatalytic TiO₂ membrane with large surface area of anatase crystallites was successfully fabricated by anodization. The nano-structured anodized TiO₂ membrane was characterized using SEM, XRD and TEM techniques and the operational parameters to fabricate such as anodization time and applied anodic potential were also investigated. The anodized TiO₂ membrane showed high photocatalytic performance in terms of refractory organics decomposition, bacteria inactivation and membrane permeability, which suggests that problems of conventional photocatalytic treatment and membrane filtration in water and wastewater treatment may be reduced using this combined process.
通过阳极氧化成功制备了具有大比表面积锐钛矿晶的自组织纳米结构光催化 TiO₂ 膜。采用 SEM、XRD 和 TEM 技术对纳米结构阳极氧化 TiO₂ 膜进行了表征，并对制备工艺参数（如阳极氧化时间和施加的阳极电位）进行了研究。阳极氧化 TiO₂ 膜在难降解有机物分解、细菌灭活和膜渗透性方面表现出高的光催化性能，这表明使用这种组合工艺可以减少传统光催化处理和膜过滤在水和废水处理中的问题。
