Fabrication and properties of photocatalyst layers with controlled porosity
 Blecha, Tomáš ; Gemeiner, Pavol (referee) ; Dzik, Petr (advisor)
This bachelor thesis deals with fabrication of photocatalyst layers with controlled porosity and investigation of their properties. Polyvinyl pyrrolidone, polyethylene glycol and polyvinyl alcohol were used as templating agents. Prepared compositions were deposited on FTO glass using a drop-casting method and annealed at 450 °C. The structure of thin films was examined using optical and electron microscopy. The thin films were subsequently studied by photoelectrochemical measurements. Most resulting compositions showed relatively good electrical and optical properties, hinting at a potential for future use in practice.

Tungsten Trioxide Thin Films Deposited by Material Printing of Aqueous Precursors
 Martinková, Eliška ; Pekárková, Jana (referee) ; Králová, Marcela (advisor)
This bachelor thesis deals with material printing of thin layers of tungsten trioxide with selected templating agents. Polyvinyl pyrrolidone, polyoxyethylene(20)cetyl ether, polyethylene glycol and Pluronic 123 were used as templating agents. These compositions were applied by the material printing method on FTO glasses and annealed at 500 °C. The structure and thickness of thin films were analyzed using a profilometer, SEM and AFM. Subsequently, the properties of thin films were studied using photoelectrochemical measurements.
