Titanium dioxide (TiO2) nanocrystals of different shape were
successfully synthesized in a new microemulsion system through a solvothermal process. The TiO2
nanocrystals were prepared from the reaction of tetrabutyl titanate (TBT), H2O, and oleic acid
(OA), which were used as solvent and surfactant at 300 degrees C and 240 degrees C in a stainless
steel autoclave. The sphere, polygon, and rhombus-shaped nanocrystals have been prepared at 300
degrees C and the dot- and- rod shaped nanocrystals have been synthesized at 240 degrees C. The
effect of the reaction time on the shape and size of TiO2 nanocrystals in this method was studied
in the present paper. The size distribution of TiO2 nanocrystals prepared at 300 degrees C for
different hours is also studied. In addition, an attempt to describe the mechanism of shape
change of TiO2 nanocrystals was presented in this paper.
