Porous layers of titanium dioxide
Sekerová, Kateřina ; Dvonka, Vladimír (referee) ; Dzik, Petr (advisor)
This thesis deals with the preparation, properties and methods of characterization of porous titanium oxide layers prepared by sol-gel process. The theoretical part contains a summary of the search methods of preparation and use of porous thin films of titanium dioxide photocatalysis. The practical part involves the preparation of sol suitable for printing of porous layers, the properties and characterization of these layers.

Photocatalytic properties of hybrid titania-silica layers
Sekerová, Kateřina ; Drbohlavová, Jana (referee) ; Dzik, Petr (advisor)
This diploma thesis is focused on the preparation of hybrid titania-silica layers. Titanium tetraisopropoxide and tetraethyl orthosilicate with Levasil were used as the precursors for TiO2 and SiO2 synthesis, respectively. The layers were deposited on substrates by material printing. Furthermore, this work is focused on the study of the rheological properties of TiO2-SiO2 sol and characterization of prepared films by XRD, SEM, ellipsometry, AFM, pencil hardnes test, optical microscopy. Optical properties were also characterized by transmitance and reflectance measurement and the functionality of these layers was demonstrated by a stearic acid degradation experiment.
