The effect of TiCl4 hydrolysis temperature on the textural properties of the resulting rutile and on the changes of these properties upon calcination was studied. The mercury porosimetry, BET, SEM and TEM studies have revealed that nanoscale rutile obtained by thermolysis of titanium tetrachloride has a multi-level packing of the particles with a heterogeneous pore structure. Raising the temperature of rutile synthesis increases the fraction of mesopores and decreases the fraction of micro- and macropores in rutile samples. As shown by the textural study of the samples upon calcination in the temperature range of 100-1000oC, the temperature mode is the key factor that produces changes at different levels of the hierarchical system and determines features of the porous structure of nanoscale rutile.
