It was found that the morphology obtained for
TAA/TiP nanomaterials depends not only on the kind of solvents
but also on the amount and alkyl chain length of the TAA used
upon the solvotermal conditions. X-ray powder diffraction patterns
of TAA/TiP samples with different morphology are shown in
Fig. 3, being observed that all have pseudolayered habit with strong
preferred orientation along the (0 0 1) reciprocal lattice direction.
Fig. 4a shows the influence of reaction time on both position
and intensity of the interlayer XRD-peak for tubular nanoparticles
when acetone is used as solvent and trihexylamine as template
molecule. The interlayer distance increases when increase the reaction
time, simultaneously to the increase of organic matter content
in the material, while the crystallinity reach maximum after 6 days.
