Abstract
We have fabricated a self-organized, nanostructured, photocatalytic TiO 2 metal membrane that has a large surface area of anatase crystallites by anodization. A nanostructured anodized TiO 2 metal membrane was characterized by SEM, XRD, and TEM, and the effects of changes in fabrication parameters, such as fluoride ion (F -) concentration and applied anodic potential, were monitored. The anodized TiO 2 membrane – which performed photocatalytic oxidation, enhanced adsorption, and membrane filtration concurrently – showed high photocatalytic activity with regard to the decomposition of organics and membrane permeability, which suggests that the problems that plague conventional photocatalytic treatments and membrane filtration of water and wastewater are mitigated with this advanced environmental material.
