Titanium dioxide (TiO₂) is widely regarded as one of the most extensively applied photocatalytic semiconductor materials. However, conventional powdered titanium dioxide exhibits certain limitations, including relatively weak light absorption capability, a small surface area and insufficient active sites. This study successfully prepared flexible and porous silicon dioxide (SiO₂)–titanium dioxide nanofiber membranes (NFMs) by implementing electrospinning technology and calcination processes. The porous membranes demonstrate remarkable performance in water treatment, featuring a high specific surface area (49 m²/g) and porosity, enabling efficient adsorption and removal of organic pollutants in water. Remarkably, the NFMs-800 variant exhibits outstanding photocatalytic performance, achieving complete removal of adsorbed organic compounds under ultraviolet irradiation. The design and fabrication methods of this porous membrane are simple and scalable, providing a potential solution for practical water-treatment applications. Consequently, the silicon dioxide–titanium dioxide porous membrane holds significant prospects in the field of water treatment, offering a promising contribution to the attainment of efficient and sustainable water resource management.

使用柔性 SiO2-TiO2 纳米纤维膜增强亚甲基蓝染料的降解

二氧化钛（TiO ₂）被广泛认为是应用最广泛的光催化半导体材料之一。然而，传统的粉状二氧化钛存在一定的局限性，包括光吸收能力相对较弱、表面积较小和活性位点不足。本研究通过静电纺丝技术和煅烧工艺成功制备了柔性多孔二氧化硅（SiO ₂）-二氧化钛纳米纤维膜（NFM）。该多孔膜在水处理中表现出卓越的性能，具有高比表面积（49 m ² /g）和孔隙率，能够有效吸附和去除水中的有机污染物。值得注意的是，NFMs-800 变体表现出出色的光催化性能，在紫外线照射下实现了吸附有机化合物的完全去除。这种多孔膜的设计和制造方法简单且可扩展，为实际水处理应用提供了潜在的解决方案。因此，二氧化硅-二氧化钛多孔膜在水处理领域具有广阔的前景，为实现高效和可持续的水资源管理做出了有希望的贡献。
