| Abstract | dc.description.abstract | The effect of the neutral surfactant dodecylamine and octadecylamine on the synthesis of
TiO2-based nanostructures by the treatment of anatase with NaOH under hydrothermal conditions in
the temperature range 120–150 C and different reaction times was investigated. The products analyzed
by electron microscopy, X-ray diffraction, FT-IR and elemental analysis contains—depending
of the amine, the temperature and the duration of the hydrothermal treatment—spherical and tubular
species containing the acid H2Ti3O7. The formation of morphologically almost pure phases constituted
by nanospheres and nanotubes were obtained at 130 C after about 30 and 50 h respectively.
Using dodecylamine, structurally fragile tubular amine containing nanocomposites are obtained,
while in the case of the octadecylamine, notoriously stable purely inorganic nanotubes are formed.
The role of the amine in these reactions is discussed | es_CL |
