Abstrakt: 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
