Preparation and characterization of TiO2 films deposited by liquid phase
 Szatmáry, Lórant ; Šubrt, Jan ; Bezdička, Petr ; Jirkovský, Jaromír ; Kete, M. ; Štangar, U. L.
The aim of this work was to prepare the TiO2 layer at different reaction temperatures and to determine the effect of composition and temperature on the photocatalytic activity.

Low-temperature inorganic synthesis and photocatalytic activity of anatase TiO2 powders
 Tasbihi, M. ; Štangar, U. L. ; Černigoj, U. ; Jirkovský, Jaromír
Nowadays, it is a great challenge to synthesize different crystalline TiO2 using low temperature methods without calcination step. In our study, the nanocrystalline titanium dioxide sols were prepared from TiCl4 under acidic conditions. The powder was obtained with consequent drying of the sols at temperatures below 100 oC and these samples were then characterized using different techniques. The results show that the properties of the asprepared powders depend mainly on the type of the acid and less on the amount of the acid. The usage of HClO4 instead of HNO3 as the peptizing agent results in colloids with higher photocatalytic activity
