We report on the fabrication process of TiO2
-based aeromaterial for environmental applica tions, such as wastewater treatment or as activated photocatalytic air filters. The TiO2
aeromate rial is obtained by Atomic Layer Deposition technique with the thickness of 50 nm on a substrate template consisting of ZnO microtetrapods, followed by the selective chemical etching of the
ZnO template. The morphological and optical properties, chemical composition and crystalline
quality of the fabricated aeromaterial are investigated. By implementing specific technological
steps to enhance the crystalline quality of the TiO2
aeromaterial, it was possible to obtain materi als with either anatase phases or a mixed anatase-rutile phase.
