Photocatalytically active filtration systems based on modified with titanium dioxide PET-membranes

Abstract Photocatalytically active nanostructured filtration systems are formed by two-step hydrolysis of titanium dioxide on the surface of polyethylene terephthalate ion-track membranes. Characterization of the morphological and structural properties of the nanosized TiO 2 deposit obtained under various conditions on the surface of ion-track membranes is carried out, and the correlation of the TiO 2 parameters with the synthesis conditions is established. The absorption spectra of the obtained systems were measured. Methods of the enhancing the operating wavelength range to increase the efficiency of potential application of photocatalytically active nanostructured TiO 2 systems under the influence of sunlight are discussed.
