Abstract
The nucleation and growth mechanisms of hydrothermal synthesized nanotitanates are proposed based on the interaction effect
between agitation condition and pristine titania particle size. TEM examination and N2 adsorption measurements revealed distinct morphology and textural properties depending on TiO2 particle size in constant agitation condition. Regarding to the supersaturation degree, heterogeneous nucleation dominates
for nanotubes formation from large particle size of raw material. On the other hand, homogeneous nucleation determines nanospheres
formation from small particle size of raw material. The nanotubes have an outer diameter ranging from 8 to 10 nm and inner
diameter of 2 to 3 nm. The nanospheres have diameters ranging from 50 to 100 nm.
