Novel photoactive nano-filtration modules composed of a nano-particle TiO₂ loaded polyvinyl alcohol (PVA) nano-fibrous membrane on sponge Al₂O₃ scaffolds and concentric multi-layered Al₂O₃-(m-ZrO₂)/t-ZrO₂ composites were successfully prepared using the electro-spinning method, which was also used to load TiO₂ into the PVA nano-fiber. The diameter of the PVA-TiO₂ nano-fibers was approximately 200 nm. Nano-particle TiO₂ with a highly crystalline structure at a ratio of 50% were well-dispersed in the PVA nano-fibrous material. In addition, the PVA-TiO₂ membrane was found in the crystallize structure. Methyl Orange (MO) was degraded and became discolored after 5 h of oxidation by the nano-filtration membranes under UV irradiation. Sponge Al₂O₃ scaffolds and Al₂O₃-(m-ZrO₂)/t-ZrO₂ composites were successfully coated with PVA-50%TiO₂ fibers with the goal of fabricating a novel nano-filtration membrane.
